Q1. Who is the Tiger King? Why does he get that name?

ANSWER:
Jilani Jung Jung Bahadur, the king of Pratibandapuram, is known as the Tiger King. At the time of his birth the astrologers declared that the prince would have to die one day. The ten-day-old prince asked the astrologers to reveal the manner of his death. The wise men were baffled at this miracle. The chief astrologer said that his death would come from the tiger. The young prince growled and uttered terrifying words: ‘Let tigers beware!’ He decided to kill one hundred tigers. He thus got the name ‘Tiger King’.

Q2. What did the royal infant grow up to be?

ANSWER:
The royal infant grew up to be the king of Pratibandapuram who was obsessed with the idea of killing one hundred tigers. He wanted to do so to disprove the prophecy which said that his death would come from the hundredth tiger. This made him kill all tigers of Pratibandapuram. He even married for the sake of this ambition. He came to be known as the Tiger King.

Q3. What will the Maharaja do to find the required number of tigers to kill?

ANSWER:
To get the required number of tigers to kill, the Maharaja asked his dewan to find a suitable girl for him to marry. A suitable girl for matrimonial alliance would be one who would not only come from a royal family but also belong to a state with a large tiger population. As Pratibandapuram had no more tigers left, a province that belonged to his father-in-law would certainly provide him with an opportunity to kill more tigers and reach his aim of killing one hundred tigers.

Q4. How will the Maharaja prepare himself for the hundredth tiger which was supposed to decide his fate?

ANSWER:
The Maharaja wanted to be extremely careful while dealing with the hundredth tiger which was supposed to be the reason for his death. On encountering the hundredth one, he took a careful aim at the tiger and shot it. When it fell in a crumpled heap, he was overcome with joy and left the place hastily.

Q5. What will now happen to the astrologer? Do you think the prophecy was indisputably disproved?

ANSWER:

The astrologer dies before the king of Pratibandapuram gets an opportunity to kill one hundred tigers. Disproving his prophecy seems to be the sole reason for the king’s existence. Except for killing hundred tigers, everything else takes a back-seat for the king.
The prophecy cannot to be indisputably disproved as the king was ultimately killed by a tiger, though neither by a real one nor by the hundredth one. Looking at the weak, old and almost lifeless tiger that was the hundredth one, no one would have thought that it would escape the king’s bullet by fainting at the shock of the bullet whizzing past. It was the “tiny little wooden tiger” from the toy shop that caused the death of Tiger King.

Reading with Insight
Q1. The story is a satire on the conceit of those in power. How does the author employ the literary device of dramatic irony in the story?

ANSWER:
The story “The Tiger King” is a supreme example of dramatic irony. The character acts in a way grossly inappropriate to the actual circumstances or expects the opposite of what fate holds in store for him’. Kalki has used a very dexterous use of dramatic irony in the story. After killing the first tiger the King flaunts its dead body before astrologer to show that he is more powerful than the tiger. However, the astrologer warns the king that he should be “careful with the hundredth tiger”. The king chooses to prove the astrologer wrong once again and makes frantic efforts to kill hundred tigers. Thus, having shot at the old tiger, the Tiger king believes he has killed the hundredth tiger. But the reader as well as the king’s officers and minions soon come to know that the emaciated tiger does not get killed but only faints. The king gets happy of killing the tiger but in actual ignorant of this ironical fate the prediction proves to be right and mere sliver on wooden tiger’s body causes his dramatic death. Quite ironically the hundredth tiger kills the king instead and astrologer’s predictions stands vindicated.

Q2. What is the author’s indirect comment on subjecting innocent animals to the willfulness of human beings?

ANSWER:

Through this satirical story the author has rightly portrayed how human beings have subjected innocent animals to untold torture and death, merely to fulfill their own whims and fancies. The maharaja’s indiscriminate killing of tigers led to their extinction in some states, but the maharaja was oblivious to the grave consequences his action was leading to. In order to prove an astrologer wrong the maharaja went on a killing spree proving his dominance over the hapless animals.

Q3. How would you describe the behaviour of the Maharaja’s minions towards him? Do you find them truly sincere towards him or are they driven by fear when they obey him? Do we find a similarity in today’s political order?

ANSWER:
Maharaja’s minions were subservient and sycophantic. Most of them were scared of Maharaja and tried to keep him in good humour by obeying his orders. They did not dare to disobey him as his displeasure could mean loss of their job or even loss of their lives.
The astrologer was afraid of predicting his death , till Maharaja told him to “ speak without fear”. Dewan who should have advised the king not to kill the tigers did not dare to go against his wishes and aided his marriage to a princess whose father’s kingdom possessed a large number of tigers. Being afraid of losing his job, he presented an old tiger to satisfy the whims of his Maharaja. Likewise , the hunters chose not to inform him of the survival of the 100th tiger and instead killed it themselves fearing that they might lose their jobs. Even the shopkeeper, who sold the king a cheap wooden toy tiger, quoted a higher price lest he should be punished under the rules of emergency.
So ,it is evident that the king’s minions were driven by fear rather than any feelings of sincerity towards their ruler.
Today’s political order is no different. We know too well that many of the people in power are not there because of their ability but because of their influence and power. Moreover, others pander to them for their own vested interests rather than for the good of the country.

Q4. Can you relate instances of game-hunting among the rich and the powerful in the present times that illustrate the callousness of human beings towards wildlife?
ANSWER:
There have been some instances of game hunting in the present times. Even the affluent have been involved in instances that illustrate the callousness of human beings towards wildlife.
Salman Khan – Black Buck poaching case.
Nawab Mansoor Ali Khan Pataudi – Antelope case.

This name is often shortened to the Tiger King.

Q2.What does the author consider imperative right at the start?
ANSWER:  Author considers it imperative to disclose a matter of vital importance about the Tiger King. He was a man of indomitable courage. Eveiyone who reads of him will have a natural desire to meet him face-to-face. But there is no chance of its fulfilment as the Tiger King is dead.

Q3. Which matter about the Tiger King is of extraordinary interest?
ANSWER:  The manner of the death of the Tiger King is of extraordinary interest. The most fantastic aspect of his demise was that as soon as he was bom, astrologers had foretold that one day the Tiger King would actually have to die.

Q4. What was the great miracle that took place? What was its result?
ANSWER:  The astrologers said the child bom under that particular star would one day have to meet its death. At that very moment a great miracle took place. An astonishing phrase emerged from the lips of the ten-day-old Jilani Jung Jung Bahadur, “O wise prophets!” Everyone stood motionless with astonishment and stupidity.

Q5. What did the infant born just ten days ago tell the wise astrologers?
ANSWER: The infant said that all those who are bom will one day have to die. So he did not need their predictions to know that. He further said that there would be some sense in it if they could tell him the manner of his death.

Q6. Why did the Maharaja order the dewan to double the land tax? [All India 2014]
ANSWER:  Maharaja went out on an expedition to find the hundredth tiger. The tiger could not be found. That is why in anger he ordered the dewan to double the land tax.

Q7. How did the chief astrologer react to the infant prince’s observation ?
ANSWER:  The chief astrologer was surprised. He placed his finger on his nose in wonder. It was incredible that the ten-day-old infant raised intelligent questions. He said that the prince was bom in the hour of the Bull. The Bull and the Tiger are enemies. Therefore, death comes from the Tiger.

Q8. How did the crown prince Jung Jung Bahadur grow up?
ANSWER:  The infant had an uneventful childhood. He grew up just like other royal princes of Indian states during the British rule. The prince grew taller and stronger day by day. The boy drank the milk of an English cow. He was brought up by an English nanny and tutored in English by an Englishman. He saw nothing but English films.

Q9. How does the author satirise the upbringing and education of crown princes of Indian states?
ANSWER:  The author makes us laugh by pointing out the excessive love of the Indian kings and queens for English education and English way of fife. They seemed so enamoured of everything English that the crown princes drank the milk of English cows, were brought up by English nannies and tutored in English by Englishmen. They saw only English films. Thus, they were Indians only in flesh and blood, but aped Englishmen in culture and manners.

Q10. Why did the Maharaja ban tiger hunting in the state? [Delhi 2014]
ANSWER:  Maharaja banned the tiger hunting in the state. Because he wanted to prove the predictions of state astrologer wrong that he would be killed by the hundredth tiger. That is why he put a ban on the hunting of tigers on all the tiger-rich forest of Pratibandapuram.

Q11. Why, do you think, did the Maharaja send for the State astrologer?
ANSWER:  The Maharaja was excited beyond measure when he killed his first tiger. He felt proud of his feat. He wanted to show the dead beast to the State astrologer. So, he sent for him and wanted to know what he said then.

Q12. Sum up in your own words the interview between the Maharaja and the State astrologer.
ANSWER:  On the orders of the Maharaja, the State astrologer said that his majesty might kill ninety- nine tigers in exactly the same manner. But he must be careful with the hundredth tiger. The Maharaja observed that the hundredth tiger might also be killed. What will happen then? The astrologer said that then he would tear up all his books on astrology and set fire to them. Moreover, he would cut off his tuft, crop his hair short and become an insurance agent.

Q13.Point out the irony in the statement: “From that day onwards it was celebration time for all the tigers inhabiting Pratibandapuram.”
ANSWER:  The state banned tiger hunting by anyone except the Maharaja. An official statement was issued. If anyone dared to harm a tiger even by flinging a stone at him, all his wealth and property would be confiscated. The tigers could rejoice that they would not be killed by the riff-raff. The irony is that they were set to die at the hands of the Maharaja. The bullets of his gun awaited them.

Q14.Hew did the Maharaja devote himself to realise his ambition? How far did he succeed?
ANSWER:  The Maharaja pursued his ambition with single minded devotion. He vowed that he would attend to all other matters only after killing the hundred tigers. He bravely faced many dangers to his life from tigers in achieving his mission. Sometimes he had to fight a tiger with his bare hands. But each time the Maharaja proved victorious by killing the beast.

Q15.Why, do you think, was the Maharaja in danger of losing his throne ?
ANSWER:  The Maharaja had annoyed a high-ranking British officer by refusing him permission to hunt tigers in Pratibandapuram. The Maharaja did not relent even when the request was toned down that the durai himself did not have to kill the tiger. The Maharaja could do the actual killing. The durai wanted only a photograph of himself holding the gun and standing over the tiger’s carcass. The Maharaja stood in danger of losing his throne because he prevented a British officer from fulfilling his desire.

Q16.What traits of the Maharaja and the British officer are exposed and satirised through the episode of refusal of permission for tiger hunt by the British officer?
ANSWER: It reveals that the Maharaja was wilful, obstinate and adamant. He had a false sense of honour. If he had permitted one British officers, others would also turn up. He is quite unreasonable and shows lack of understanding. Thus, he lacks practical approach. He would sacrifice diamonds to preserve his throne.
The British officer seems publicity conscious. He is more interested in the photographs with the dead-tiger than in the tiger-hunt. The costly gift of diamonds mollifies his hurt ego.

Q17. Would it be proper to call the Maharaja ‘penny-wise, pound foolish’? Give reasons for your answer.
ANSWER:  The Maharaja insists on restricting tiger-killing in his state to himself. He is unwilling to compromise in this regard. He would not let any other person be even photographed with a dead tiger in his state. He has to send a gift of fifty diamond rings to the British officer’s good lady to placate the injured feelings of the man and to retain his kingdom. It illustrates that he was penny-wise, pound foolish.

Q18. What sort of hunts did the Maharaja offer to organise for the high-ranking British officer ? What trait of the persons in high position does it reveal ?
ANSWER:  The Maharaja offered to organise any other hunt in place of the tiger hunt for the high- ranking British officer. He might go on a boar-hunt. A mouse-hunt might be conducted. They were ready even for a’ mosquito-hunt. This shows the vanity and love of idle pursuits and frivolous pastimes by the persons in high position.

Q19.Comment on the ‘rings episode’ in the story ‘The Tiger King’.
ANSWER:  The Maharaja of Pratibandapuram ordered a famous British company of jewellers in Calcutta to send samples of expensive diamond rings of different designs. Some fifty rings arrived. The Maharaja sent the whole lot to the British officer’s good lady. He expected her to choose one or two rings and send the rest back. But she simply sent a letter of thanks.
The episode reveals human weaknesses such as vanity, pride, greed, cunningness, flattery and appeasement.

Q20……. an unforeseen hurdle brought his mission to a standstill”. What was the mission and how did it stop? What do you find amusing in the reasons justifying the ‘hurdle’?
ANSWER: The Maharaja’s mission was to shoot one hundred tigers. He had killed seventy tigers within ten years. Then the tiger population became extinct in the forests of Pratibandapuram. The possible reasons for the absence of tigers are quite amusing and even ludicrous. Either the tigers practised birth control or they committed suicide. They might have run away from the state. Perhaps they desired to be shot by the British hands alone.

Q21.How did the dewan behave when the Maharaja summoned him and brandished his gun?
ANSWER:  The dewan shuddered at the sight of the gun. He cried out, “Your Majesty! I am not a tiger!” The Maharaja enquired which idiot would call him a tiger. The dewan then declared that he was not a gun. The Maharaja became a bit polite. Addressing him as ‘Dewan Saheb’ he assured him that he was neither tiger nor gun. He was summoned there for a different purpose.

Q22. How did the dewan react to the Maharaja’s declaration. “I have decided to get married”?
ANSWER:  The reaction of the dewan is quite funny and amusing. He thinks that the Maharaja wants to marry him. He says that he has already two wives. The Maharaja clarifies that he does not want to marry him. He wants a tiger. The dewan interrupts him saying that his ancestors were married to the sword. He might marry the gun if he liked. He added that a Tiger King was more than enough for that state. It did not need a Tiger Queen as well.

Q23. How did the Maharaja make his intentions clear to the dewan ? What, do you think, is his first priority in marriage ?
ANSWER:  The Maharaja said that he was not thinking of marrying either a tiger or a gun. He wanted to marry a girl from the ranks of human beings. He asked the dewan to collect statistics of tiger population in the different native states. Then he should find out if there was a girl he could marry in the royal family of the state with a large tiger population. Evidently, his first priority is the tiger,

Q24.How did the Maharaja succeed in raising his tiger tally to ninety-nine?
ANSWER:  The Maharaja married a girl from a state which possessed a large number of tigers. Each time he visited his father-in-law, he killed five or six tigers. In this manner he raised the tally of tigers killed by him from seventy to ninety-nine.

Q25.Why was the Maharaja so anxious to kill the hundredth tiger?
ANSWER:  The Maharaja had killed ninety-nine tigers. If he could kill just one more tiger, he would have no fear left. Then he could give up tiger hunting altogether. He thought of the tiger during the day and dreamt of it at night. Moreover, he had to be extremely careful with that last tiger. The late chifef astrologer had already warned him.

Q26.“It seemed easier to find tiger’s milk than a live tiger” Why? What does the contradiction imply?
ANSWER:  As the Maharaja reached near the coveted figure of hundred, his difficulties also multiplied. He had already killed ninety-nine tigers, but then the tiger farms ran dry even in his father-in-law’s kingdom. It became impossible to locate tigers anywhere. The hundredth tiger seemed difficult to find. One can’t get tiger’s milk without finding the tigress. Yet it is thought easier than finding a live tiger. The contradiction implies the difficulty in locating a tiger.

Q27.Why was the Maharaja sunk in gloom? Was he able to overpower it? How /How not?
ANSWER:  Only one tiger remained to be killed by the Maharaja, but it seemed impossible to locate a tiger. So, the Maharaja was sunk in gloom. Then he got the happy news. In his own state sheep began to disappear frequently from a hillside village. It was found out that this was not the work of Khader Mian Saheb or Virasami Naicker. Both of them could swallow sheep whole. It was then deduced that it was the work of a tiger. The villagers ran to inform the Maharaja about the availability of a tiger.

Q28.What aspects of the Maharaja’s nature and conduct does the wait for the hundredth tiger reveal?
ANSWER: The wait for the hundredth tiger reveals the royal rage, obstinacy and firm determination of the Maharaja. He refused to leave the forest until the tiger was found. Many officers lost their jobs because of his anger. Even the dewan was asked to resign his post. This shows that the Maharaja was insensitive towards his employees.

Q29.How, do you think, did the dewan try to help the Maharaja achieve his mission?
ANSWER:  The aged dewan was very wise. He brought an old tiger from the People’s Park in Madras. He kept it hidden in his house. Judging the impatience of the Maharaja to shoot the tiger, he decided to release it near the Maharaja’s camp. So, at midnight he dragged the tiger to the car with the help of his aged wife and shoved it into the seat. He drove the car himself straight to the forest and hauled the beast out of the car and pushed it down to the ground near the Maharaja’s camp.

Q30.How does the tiger behave towards the dewan, the Maharaja and the hunters? What does his behaviour show?
ANSWER:  The tiger behaves like a pet animal with the dewan. The dewan and his aged wife drag the tiger to the car and shove it into the seat. In the forest, the tiger launches its satyagraha and refuses to get out of the car. The Dewan tries hard to haul it out of the car and push it down to the ground.
It stands before the Maharaja as if in humble supplication. It falls down in a crumpled heap as the Maharaja fires the gun. It faints from the shock of the bullet whizzing past. It looks back at the hunters rolling its eyes in bafflement. This shows that it is a very old and weak tiger.

Q31.“The bullet had missed it.” “This time he killed it without missing his mark.” Whose bullet had missed the tiger? How was the beast killed ultimately? Bring out the irony of the situation.
ANSWER:  The Maharaja’s bullet missed the tiger though he had taken careful aim at the beast. The shock of the sound of the bullet made it faint. One hunter took aim from a distance of one foot and shot the tiger dead.
It is ridiculous that the Tiger King who had killed ninety-nine tigers should miss his aim. It is funny that the hunter takes aim from a hand-shaking distance. The whole situation is ironic.

Q32. How does the hundredth tiger take its final revenge upon the Tiger King?
ANSWER:  The Tiger King could not kill the hundredth tiger. It had merely fainted from shock of the sound of the bullet. It is the wooden tiger from the toyshop that becomes the cause of Maharaja’s death. One of the slivers on its body pierces the Maharaja’s right hand. Infection flares up and the prick develops into a suppurating sore. The Maharaja dies during the operation.

LONG ANSWER TYPE QUESTIONS :


Q1. What do you learn about princes and kings of native Indian states during the British rule from the story ‘The Tiger King’?
ANSWER:  The story ‘The Tiger King’ presents a fair glimpse of the young princes and the Maharajas ©f native Indian states. Their long names with descriptive titles and decorative honours was more a rule than an exception. They considered recognition from the British government and its officers a favour. They aped the Britishers in upbringing, education, manners and behaviour. The Maharajas were autocrats and their words were the law. They could be benevolent as well as stubborn. Their minions as well as ministers feared and respected them. Sometimes their whims proved quite costly to the state coffer. The Maharaja of Pratibandapuram spends three lakh of rupees on gift of diamond rings to retain his kingdom. Marriages with princesses of other states are based on considerations other than love or virtues of the girl. In short, the Princes and Maharajas are portrayed as whimsical, stubborn and excitable persons proud of their virtues and valour.

Q2. What did the astrologers predict about the infant prince ? What was the miracle that baffled them. ? What did the chief astrologer enlighten the prince about and how ?
ANSWER:  As soon as the prince was bom, astrologers predicted that one day the Tiger King would certainly have to die. It was the influence of the star under which he was bom. At that very moment a great miracle took place. An astonishing phrase emerged from the lips of the ten-day-old Jilani Jung Jung Bahadur, “O wise prophets!” Everyone stood motionless with astonishment and stupidity. The infant said that all those who are bom will have to die one day. So he did not need their predictions to know that. However, there would be some sense in it if they could tell him the manner of that death.
The astrologers were baffled that a baby barely ten-day-old has not only opened his lips in speech but had also raised intelligent questions. It was quite incredible. The chief astrolo¬ger fixed his eyes upon the little prince. He said that the prince was bom in the hour of the
Bull. The Bull and the Tiger are enemies. Therefore, death comes from the Tiger.

Q3. How did the Maharaja try to disprove the prediction of the chief astrologer? What did the state astrologer assert when the Maharaja summoned him to show his first kill?
ANSWER:  Since the astrologers had predicted death from Tiger, the Maharaja decided to kill tigers to defend himself. Hence he started out on a tiger hunt campaign. There were enough tigers in the forests of Pratibandapuram state. The Maharaja was thrilled beyond mea¬sure when he killed his first tiger. He sent for the state astrologer and showed him the dead beast.
The Maharaja asked the astrologer what he said then. The astrologer said that his maj-esty might kill ninety-nine tigers in exactly the same manner, but he must be very careful with the hundredth tiger. Maharaja wanted to know what would happen if the hundredth ; tiger was also killed.
The state astrologer said that in that case he would tear up all his books on astrology and ‘ set fire to them. Moreover, he would cut off his tuft, crop his hair short and become an insurance agent.

Q4. What problems did the Maharaja face in pursuit of his mission ? How did he resolve them ?
ANSWER:  The Maharaja started his mission of killing one hundred tigers with single-minded devo¬tion. He focused all his energy and attention to it. He vowed that he would attend to all other matters only after killing one hundred tigers. Initially, the king seemed well set to realise his ambition. Then dangers and difficulties cropped up. There were times when the bullet missed its mark. The tiger would leap upon him and he had to fight the wild beast with his bare hands. Luckily, each time the Maharaja, who had indomitable cour¬age, won.
Once he was in danger of losing his throne because he did not permit a high-ranking British officer to hunt a tiger in the Pratibandapuram forest. The king did not accede to his request for being photographed with a gun on the carcass of a tiger killed by the Maharaja. The Maharaja had to part with a costly gift to placate his injured feelings and save his kingdom.

Q5. How does the author satirise the hunting instincts of the persons in authority ?
ANSWER:  The story tells us that big game hunting was considered a royal sport. The Maharaja of Pratibandapuram went to the extent of banning tiger-hunt in his own kingdom by all others except himself.
Tiger-hunt became an obsession for him. He thought of tiger during the day and dreamt of it at night. He postponed all affairs of the state and devoted himself only to tiger-hunt. Thus, a pastime or sport became the only aim of his life. He married for the sake of tiger. He chose a princess in whose kingdom there were plenty of tigers. He could undertake any risks for tiger-hunt.
The British officers had also developed a fondness for this royal sport. Perhaps they considered it a status symbol. They were publicity conscious and wanted to be photographed with a gun in hand and the carcass of a tiger at feet. Various other hunts were also prevalent. These included boar-hunt, mouse-hunt and mosquito-hunt. The descending order of risk and resistance from the victims makes us laugh at the whims and craziness of the hunters. Thus, the story exposes the fondness of persons in authority for hunting wild animals.

Q6. How did the Maharaja devise a new avenue to fulfil his ambition to kill one hundred tigers? How far did he succeed?
ANSWER:  The Tiger King had resolved to kill one hundred tigers. During ten years he killed seventy tigers in his kingdom. Then the tigers became extinct in the forests of Pratibandapuram. The Maharaja devised a plan. He decided to get married. He asked the dewan to collect statistics of tiger population in different native states. Then he was assigned the job to find out if there was any girl in the royal household that he could marry. The main criterion for the selection of the princess was that her father’s kingdom should have a large number of tiger population. The dewan complied with the orders of the Maharaja. Then the Maharaja married a girl from a state which possessed a large tiger population. Each time he visited his father-in-law, he killed five or six tigers. In this way he was successful in killing niqety-nine tigers.

Q7. Give an account of the Maharaja’s impatience for the hundredth tiger and the actual encounter. What, do you think, caused the death of the Tiger King?
ANSWER:  The Maharaja was keen to kill the hundredth tiger. If he did so, he would have no fears left. It became impossible to locate tigers anywhere. When the villagers informed him of the activities of a tiger near hillside, he went to the forest and waited there. The tiger seemed to have deliberately hid himself to defy the Maharaja’s will.
The wise, aged dewan got an old tiger brought from the People’s Park in Madras. He released it at night in the forest near the Maharaja’s camp. In the morning, the same tiger wandered into the Maharaja’s presence and stood their meekly. The Maharaja took careful aim at the beast. The tiger fell down. Actually the bullet had missed it, The old tiger had fainted with the shock of the bullet passing near him.
The Tiger King died due to an infection from a tiny sliver of a wooden tiger. The prick developed into a sore with pus. A surgical operation was performed on his arm, but he died. The writer comments that the hundredth tiger took its final revenge upon the Tiger King.

Q8. Comment on the ending of the story ‘The Tiger King’. Do you find it convincing? Give reasons. 
ANSWER:  The ending of the story ‘The Tiger King’ seems tame, unconvincing and rather contrived. It seems unnatural and unrealistic. It is beyond comprehension how a king who has over powered ferocious tigers in single combat with bare hands succumbs to a prick from the sliver of a wooden tiger.
It is amazing to find how the infection flares in the Maharaja’s right hand. In four days, the prick develops into a suppurating sore and spreads all over the arm. The three sur¬geons perform a successful operation but fail to save the Maharaja. How is the operation successful then? It seems that the author wants us to believe that the astrologer was right and the hundredth tiger took its final revenge upon the Tiger King.This ending may satisfy superstitious readers with orthodox beliefs, but for the enlight¬ened minds of the age of computers and rockets it is a bitter pill to swallow.

Q9. Comment on the appropriateness of the title ‘The Tiger King’.
ANSWER:  ‘The Tiger King’ is a quite appropriate and suggestive title. It focuses attention on the hero of the story—The Maharaja of Pratibandapuram, who is also nick named the Tiger King. The story spans from his birth to death and covers all the landmarks connected with his passion—tiger-hunt. For him human relations and the affairs of the state are second¬ary. He marries a princess for the sake of a tiger. When he celebrates the third birthday of the crown prince, he brings a wooden tiger for him as a gift. It is ironic that the sliver of the wooden tiger causes his death. The overconfidence and false sense of security of the Tiger King on having killed the hundredth tiger leads to his doom. The story which begins with the prediction of death of the Tiger King right at his birth, ends with his death from a tiger. Thus, the title is quite apt.

Q10.What devices does the author use to make the story ‘The Tiger King’ humorous and interesting?
ANSWER:  The author uses many literary devices to make this story humorous as well as interest-ing. He introduces the elements of shock and surprise by making the ten-day-old baby open his lips to talk and ask intelligent questions. The predictions of the astrologers convey inevitability of death, but the man of indomitable courage i.e., the Tiger King faces the agent of death i.e., the tiger many times and comes out victorious every time.
The description of the education and upbringing of crown princes of Indian states and their craze for ‘English’ provides lots of fun. The mention of various hunts: tiger-hunt, boar-hunt, mouse-hunt, mosquito-hunt makes us laugh at the pastimes of the people in authority at the cost of innocent animals. The last two hunts seem funny and ridiculous.
The Maharaja’s thought of marrying a girl for the sake of tiger is also amusing. The behaviour of the high-ranking British officer and that of the Maharaja and his dewan at different points in the story provoke laughter and maintain the reader’s interest in the narrative.

They not only enrich us with the vast store of knowledge but also help us to learn from other’s experience and stay rooted to some basic qualities of humanity. Joining hobby classes or gym, attending social events like birthdays and weddings, going for outdoor games, interacting meaningfully through social-networking sites and writing diaries etc can also help us relieve our worries and stay focussed and disciplined in life. Simple activities like listening to music, playing with pets, an occasional dinner out, watching cinema or plays or going to places like parks etc can go a long way in helping us get rid of stress, boredom and insecurities.
Q4. Do you see an intersection of time and space in the story?

ANSWER:
Yes, there are certain instances in the story that show an intersection of time and space. Firstly, the first two levels of Grand Central Station were located in the present time while the third level existed in the 1890s. Secondly, Charley and his wife, Louisa, live in the present time yet he rushes to get old currency to buy two tickets to go to the Galesburg of 1894. Further, the old architecture of the platform at the third level is different from the modern platforms of the first two levels. Besides, the archaic manner of dressing by the people, and the newspaper, The World, dated June 11, 1984 also overlaps with Charley’s real time world and existence. Lastly, the letter that was mailed to Charley’s grandfather on 18th July, 1894 highlights the intersection of time and space as the sender (Charley’s friend Sam) and receiver (Charley himself) belong to the present time.

Q5. Apparent illogicality sometimes turns out to be a futuristic projection? Discuss.

ANSWER:
It is true that apparent illogicality sometimes turns out to be a futuristic projection. Before the Wright Brothers invented the first aeroplane, nobody could have dared to believe that man could fly. Before Alexander Graham Bell invented the telephone, it would have been impossible to believe in long-distance talks happening in the real-time interface. Moreover, there are examples of inventions, like that of inventing a modern-day sewing machine with a needle that has hole on its wrong end, which were conceived in dreams but now are part of our everyday reality.
All this emphasises that fantasies of one point of time that seem illogical may turn out to be revolutionary things that change the future of the mankind. Similarly, it would not be far-fetched to think about railway stations fitted with time-machine devices that would make travel from one era to another just a matter of time.

Q6. Philately helps keep the past alive. Discuss other ways in which this is done. What do you think of the human tendency to constantly move between the past, the present and the future?

ANSWER:
Besides philately, there are numerous other ways to help keep the past alive. Collecting historical artefacts, paintings and inscriptions in a museum, collecting and reading books (including autobiographies, bio-sketches, letters and diary entries) written in different eras, collecting and viewing documentaries and other videos are all a few ways of revisiting history. Besides, we can keep our culture and traditions alive when we follow the rituals in ceremonies, treasure memories in the form of videos, photographs and audio collections. Also, reviving old monuments, buildings and other artefacts may prove a huge learning opportunity to those visiting such places, and promote tourism at the same time.
The capacity to oscillate between the past, present and future is a great intellectual gift. This human tendency enables him to plan for the future in the present by reaping benefits from the past. Consider a very simple example of adopting a study technique for board exams. Considering the past result (of class test or half yearly exams) a student makes a strategy plan to address the weak areas more and score better in the future. Thus, such a tendency helps in ensuring acceptance of the impact of important decisions taken at any point of time and learning from them

Q7. You have read ‘Adventure’ by Jayant Narlikar in Hornbill Class XI. Compare the interweaving of fantasy and reality in the two stories.

ANSWER:
In ‘Adventure’ Jayant Narlikar expressed that many world exist simultaneously though they appear to be separated by time. He expressed that the other world also existed and prospered with the world we are aware of. On the other hand, In the third level, Charley a young new york commuter wandering Grand Central Station by accident finds a gateway that leads to a real past of 1894Seizing the oppurtunity Charley attempts to escape the rat race by buying a one way ticket to his childhood town of Galesburg. Not having proper currency for that period, he forced to postpone his plan to escape to the past.

Aunt Jennifer’s Tigers Summary NCERT SOLUTION CLASS 12TH ENGLISH FLAMINGO | EDUGROWN NOTES

Before you Read
Q1.What does the title of the poem suggest to you? Are you reminded of other poems on tigers?

ANSWER:
The title, “Aunt Jennifer’s Tigers”, suggests that the poem is about Aunt Jennifer’s knitted tigers that, with their chivalric, ferocious, bright and carefree attitude, become an alternate world of her creation. The tigers are the only means of free expression in her life, which is otherwise burdened by fear and struggles of the married life.
There are many other poems written about tigers, some of which are given below.
“The Tiger” by William Blake
“Tiger” by Alec Derwent Hope
“Tiger Drinking at Forest Pool” by Ruth Padel

Think it Out

Q1. How do ‘denizens’ and ‘chivalric’ add to our understanding of the tiger’s attitudes?

ANSWER:
Like all beasts of prey, the tigers are the denizens of forest. They live far away from human settlements. They are called ‘chivalric.’ This indicates the majestic and honourable position that they occupy in the world of animals. So the use of the words ‘denizens’ and ‘chivalric’ adds to our understanding of the tigers’ attitudes.

Q2. Why do you think Aunt Jennifer’s hands are ‘fluttering through her wool’ in the second stanza? Why is she finding the needle so hard to pull?

ANSWER:
Aunt Jennifer’s hands are ‘fluttering through her wool’ because she is an old lady on whom age has taken its toll. The fluttering of Aunt Jennifer’s fingers also signifies her oppressed mental condition which makes it difficult for her to even pull an ivory needle while embroidering.

Q3. What is suggested by the image ‘massive weight of Uncle’s wedding band’?

ANSWER:
The ‘wedding band’ that the poet talks about was the wedding ring worn by Aunt Jennifer. The image ‘massive weight of Uncle’s wedding band’ suggests that she was overburdened with duties and responsibilities, post her marriage.

Q4. Of what or of whom is Aunt Jennifer terrified with in the third stanza?

ANSWER:
Even after death, Aunt would carry her fear of her domineering husband as she would yet bear the burden of the wedding band on her finger. The ordeals faced by her in an oppressive marriage would continue to terrify her


Q5.What are the ‘ordeals’ Aunt Jennifer is surrounded by? Why is it significant that the poet uses the word ‘ringed’? What are the meanings of the word ‘ringed’ in the poem?
ANSWER: Aunt Jennifer has been living her life in accordance with the rules laid down by her husband. Her life lacks expression and is overburdened by the demands and duties of her married life. Although old and weak, she still has to face oppression by her husband. These are the ordeals that the poet talks about.
The use of word ‘ringed’, in the poem, is significant and appropriate because it correctly represents the vicious circle from which Aunt Jennifer is unable to free herself. The word ‘ringed’ not only indicates that she is wearing her wedding ring but also that she is bound by the responsibilities, fear and oppression of her marriage for entire life and, probably, after it too.
Q6. Why do you think Aunt Jennifer created animals that are so different from her own character? 
What might the poet be suggesting, through this difference?
ANSWER:
The timid and fearful Aunt Jennifer creates an alternative world of free and fearless tigers to express her longing for freedom, a medium of escape from her grim marriage.
The ironical contrast underscores a warning by the poet against acceptance of subjugation by women as it crushes their dreams, individuality and a full life.
Q7. Interpret the symbols found in this poem.

ANSWER:
Wedding band: symbol of oppression in an unhappy marriage. Marriage is socially and legally binding, making women silently accept their subjugation and male domination, especially in a patriarchal society. Its weight refers to the burden of gender expectations. Ringed means encircled or trapped, losing individuality and freedom.
Aunt Jennifer: a typical victim of male oppression in an unhappy marriage, who suffers loss of individuality, dignity and personal freedom silently. She becomes dependent, fearful and frail.
Tigers: symbolize untamed free spirit. Here they are antithesis of their creator’s personality. The use of colours implies that Aunt Jennifer’s tigers and their land are more vital and enjoy a sense of freedom far greater than her. Yellow (bright topaz) connotes the sun and fierce energy, while green reminds one of spring and vitality.
They pace and prance freely, proudly, fearless, confident and majestic in their bearing.
Embroidery: symbol of creative expression. The artwork expresses the Aunt’s suppressed desires and becomes her escape from the oppressive reality of her life.
Aunt (last stanza): as opposed to Aunt Jennifer. It shows that she has lost her identity completely, thus lost even her name.

Q8. Do you sympathise with Aunt Jennifer? What is the attitude of the speaker towards Aunt Jennifer?

ANSWER:
Yes, the character of Aunt Jennifer wins our sympathy as a reader. Her ordeals and sufferings move the reader. Even the speaker in the poem shows sympathy and pity towards her. The speaker says that even after Aunt Jennifer’s death, she will be terrified of her husband and the ordeals of her marriage.

SHORT ANSWER TYPE QUESTION:

Q1. What do you learn about^Aunt Jennifer’s tigers on reading the poem?
  ANSWER: Aunt Jennifer’s tigers were created in the panel by her own hands. They appeared to be prancing (jumping) across a screen. They looked sleek. They were bright like yellow topaz. They were majestic and courageous. They didn’t fear the men beneath the tree. They paced in ‘chivalric certainty’.

Q2. How has Aunt Jennifer created her tigers? What traits of tigers do they reveal!
ANSWER:  Aunt Jennifer’s tigers are her own creations. She works with wool and ivory needles. She has created them in the panel. They have all the traits of the beasts of prey who are denizens of green forests. They are well-built and well-groomed. They are chivalric and full of confidence.

Q3. What difficulty does Aunt Jennifer face while making her tigers and why ?
ANSWER:  Aunt Jennifer is making her tigers in the panels. She is using ivory needles. Her fingers are fluttering through the wool. She finds it difficult (hard) to pull even the ivory needles. The reason is obvious. The weight of unhappy and unfortunate experiences of her married life sits heavily on her hands.

Q4. What is the weight that lies heavy on Aunt Jennifer’s hand? Hou: is it associated with her husband?
ANSWER:  Aunt Jennifer is working with ivory needles and wool. But she can’t move her fingers freely in the wool. She finds it hard to pull even the ivory needles easily. The experiences
of her past married life are quite bitter. She has unpleasant memories of her married life with her husband. The heavy weight of the wedding band sits heavily upon her hand.

Q5. How will Aunt Jennifer’s hands look when she is dead?
ANSWER:  When Aunt Jennifer dies, her hands will still look terrified. Perhaps she has experienced a lot of hardships and troubles in the past. Their effect has left its print on her hands. The ordeals that crushed her married life had sorrounded and cramped her fingers and hands too.

Q6. What will happen to Aunt Jennifer’s tigers when she is dead?
  ANSWER: Aunt Jennifer’s tigers will survive her. She has created the tigers in a panel. They are made of wool. These objects of art will survive their creator. The tigers will go on jumping, proud and unafraid.

Q7. Describe the poetic devices used in the poem Aunt Jennifer’s Tigers’.
ANSWER:  Adrienne Rich’s Aunt Jennifer’s Tigers’ a beautiful short poem rich in symbolism and imagery. The mataphor ‘bright topaz’ depicts the shining yellow complexion of her tigers. The effective use of alliteration in ‘sleek, chivalric certainty’ describes the pace of the tigers effectively. ‘The massive weight of wedding band’ symbolises ordeals and hardships of Aunt Jennifer’s married fife. The images ‘terrified hands’ and ‘ringed with ordeal’ create the effect of oppression and terror as well as captivity.

Q8. How are Aunt Jennifer’s tigers different from her?[All India 2014]
ANSWER:  Aunt Jennifer’s tigers are a picture of strength, beauty and certainty. They seem to be jumping across a screen. They “pace in sleek chivalric certainty”. They are confident and impressive. Aunt Jennifer is a weak, depressed and terrified person. Life has been a cup of woes for her. She is still in the grip of those ordeals and terrors that she faced and suffered from dining her married life. Her fingers are so ‘terrified’ that they find it hard to pull even the ivory needle. Thus, the contrast is amply highlighted.

Q9. What are the difficulties that Aunt Jennifer faced in her life? [Delhi 2014]
ANSWER: The fife of Aunt Jennifer was overburdened by the duties of her married life. Hardships and sufferings were the parts bf her married fife. She had to face oppression by her husband even though she was old and weak.

A Roadside Stand Summary NCERT SOLUTION CLASS 12TH ENGLISH FLAMINGO | EDUGROWN NOTES

Before you Read
Q1.Have you ever stopped at a roadside stand? What have you observed there?
ANSWER:
The poet believes that when we encounter a beautiful thing, even for a small moment, the pleasure remains with us forever. It leaves a lasting impression that inspires us to live life with hope and optimism.

Think about it

Q.1The city folk who drove through the countryside hardly paid any heed to the roadside stand or to the people who ran it. If at all they did, it was to complain. Which lines bring this out? What was their complaint about?

ANSWER:

“The polished traffic passed with a mind ahead,Or if ever aside a moment, then out of sorts
At having the landscape marred with the artless paint
Of signs that with N turned wrong and S turned wrong”
According to the city folk, these stalls with inartistic signboards blemish the scenic beauty of the landscape.

Q2.What was the plea of the folk who had put up the roadside stand?
ANSWER:

The rural folks pleaded pathetically for some customers to stop by and buy some of their
goods. City folks used to pass by on this road and hence the rural folk set up the roadsidehttps://30e6734ea96ae238b1b539a932e6585d.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.htmlstand to attract their attention and sell their goods.

Q3. The government and other social service agencies appear to help the poor rural people, but actually do them no good. Pick out the words and phrases that the poet uses to show their double standards.

ANSWER:

The poet criticizes the double standards of the government and other social service agencies who promise to improve the standard of living of the poor farmers and show them the rosy side of life. Yet, when the time comes to deliver their promise, they either forget them or fulfill them keeping in view their own benefits.  The poet calls them “greedy good-doers” and “beneficent beasts of prey”, who “swarm over their lives”. The poet says that these greedy people make calculated and well thought-out shrewd moves, to which the innocent, unaware farmers fall prey. These humble and simple farmers are robbed of their peace of mind by these clever people. The poet says,  “…..enforcing benefits
That are calculated to soothe them out of their wits,
And by teaching them how to sleep they sleep all day,
Destroy their sleeping at night the ancient way.”

Q4. What is the ‘childish longing’ that the poet refers to? Why is it ‘vain’?
ANSWER:
The poet thinks that the persons who are running the roadside stand, suffer from a childish longing. They are always expecting customers and waiting for their prospective customers. They keep their windows open to attract them. They become sad when no one turns up. They are always waiting to hear the squeal of brakes, the sound of a stopping car. But all their efforts go in vain.

Q5. Which lines tell us about the insufferable pain that the poet feels at the thought of the plight of the rural poor?

ANSWER:
Filled with empathy, the poet is unable to bear the plight of the unassuming and innocent rural people. The lines below show his insufferable pain: “Sometimes I feel myself I can hardly bear
The thought of so much childish longing in vain,
The sadness that lurks near the open window there,
That waits all day in almost open prayer”

These solutions are updated according to 2021-22 syllabus. These MCQS  can be really helpful in the preparation of Board exams and will provide you with a brief knowledge of the chapter.

NCERT MOST IMPORTANT QUESTIONS ON CHEMICAL BONDING AND MOLECULAR STRUCTURE

1.Give the main feature of Kossel’s explanation of chemical bonding.

Ans. Kossel in relation to chemical bonding drew attention to the following facts –

(i) In the periodic table, the highly electronegative halogens and the highly electropositive alkali metals are separated by the noble gases.

(ii) In the formation of a negative ion from a halogen atom and a positive ion from an alkali metal, atom is associated with a gain and loss of an electron by the respective atoms.

(iii) The negative and positive ions so formed attain stable noble gas electronic configurations. The noble gases have particularly eight electrons, nsnp6.

The –ve and +ve ions are stabilized by electrostatic attraction.


2.How can you explain the formation of NaCl according to kossel concept?

Ans. The formation of NaCl from sodium and chlorine can be explained as

Na ® Na+ + e

[Ne] 3s1 ® [Ne]

Cl + e ® Cl

[Ne] 3s2 3p5 . [Ne] 3s2 3p6 or [Ar]

Na+ + Cl ® Na+ Cl or NaCl.


3.Write the significance of octet rule.

Ans. Octet rule signifies –

(i) It is useful for understanding the structures of most of the organic compounds.

It mainly applies to the second period elements of the periodic table.


4.Write the Lewis structure for CO molecule

Ans. (i) The outer (valence) shell configurations of carbon and oxygen atoms are

Carbon : (6) – 1s2 2s2 2p2

Oxygen : (8) – 1s2 2s2 2p4.

The valence electrons (4 + 6 = 10)

But it does not complete octet, thus multiple bond is exhibited.

Thus,

(ii) N (2s2 2p3), O (2s2 2p4)

5 + (2 x 6) + 1 = 18 electrons.

Thus,


5.Give the Lewis dot structure of HNO3

Ans. HNO3 ®


6.What changes are observed in atoms undergoing ionic bonding?

Ans. Due to the electron transfer the following changes occurs –

(i) Both the atoms acquire stable noble gas configuration.

(ii) The atom that loses electrons becomes +vely charged called cation whereas that gains electrons becomes –vely charged called anion.

(iii) Cation and anion are held together by the coulombic forces of attraction to form an ionic bond.


7.Mention the factors that influence the formation of an Ionic bond.

Ans.Ionic bond formation mainly depends upon three factors –

(i) Low ionization energy – elements with low ionization enthalpy have greater tendency to form an ionic bonds.

(ii) High electron gain enthalpy – high negative value of electron gain enthalpy favours ionic bond.

(iii) Lattice energy – high lattice energy value favours ionic bond formation.


8.Give reason why H2+ ions are more stable than H2 though they have the same bond order.

Ans.In H2 ion, one electron is present in anti bonding orbital due to which destabilizing effect is more and thus the stability is less than that of H2+ ion.


9.How would the bond lengths vary in the following species? C2, C2 C22-.

Ans.The order of bond lengths in C, C2 and C22- is C2 > C2 > C22-.


10.Out of covalent and hydrogen bonds, which is stronger.

Ans. Covalent bond.


11.Define covalent radius.

Ans. The covalent radius is measured approximately as the radius of an atom’s core which is in contact with the core of an adjacent atom in a bonded situation.


12.Why NH3 has high dipole moment than NF3 though both are pyramidal?

Ans. In case of NHthe orbital dipole due to lone pair is in the same direction as the resultant dipole moment of the N-H bonds, whereas in NF3 the orbital dipole is in the direction opposite to the resultant dipole moment of the three N-F

bonds. The orbital dipole become of lone pair decreases, which results in the low dipole moment.


13.Draw the resonating structure of NO3

Ans.


14.On which factor does dipole moment depend in case of polyatomic molecules.

Ans.The dipole moment of the polyatomic molecule depends on individual dipole moments of bonds and also on the spatial arrangement of various bonds in the molecule.


15.Dipole moment of Be F2 is zero. Give reason.

Ans. In BeF2 the dipole moment is zero because the two equal bond dipoles point in opposite directions and cancel the effect of each other.

In This Post we are  providing Chapter-3 CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES NCERT MOST IMPORTANT QUESTIONS for Class 11 CHEMISTRY which will be beneficial for students. These solutions are updated according to 2021-22 syllabus. These MCQS  can be really helpful in the preparation of Board exams and will provide you with a brief knowledge of the chapter.

NCERT MOST IMPORTANT QUESTIONS ON CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

Question 1.
Calculate the energy required to convert all atoms of magnesium to magnesium ions present in 24 mg of magnesium vapors. IE1 and IE2 of Mg are 737.76 and 1450.73 kJ mol-1 respectively.

Answer:
Mg (g) + IE1 → Mg+ (g) + e (g)
IE1 = 737.76 kJ mol-1

Mg+ (g) + IE2 → Mg2+ + e (g)
IE2 = 1450.73 kJ mol-1

Total amount of energy needed to convert Mg (g) into ,
Mg2+ ion = IE1 + IE2

Now 24 mg of Mg = 241000 g = 241000×24 mol [1 Mole of Mg = 24 g]
= 10-3 mole.

Question 2.
The IE1 and IE2 of Mg. (g) are 740 and 1450 kJ mol-1. Calculate the percentage of Mg+ (g) and Mg2+ (g) if 1 g of Mg (g)
absorbs 50 kJ of energy.

Answer:
No. of moies of Mg vapours present in I g = 124 = 0.0147

Energy absorbed to convèrt Mg (g) to Mg+ (g) = 0.0417 × 740
=30.83 kJ

Energy left unused = 50 – 30.83
= 19.17 kJ
Now 19.17 kJ will be used to e Mg+ (g) to Mg2+ (g) .
∴ No. of moles of Mg+ (g) converted to Mg2+ (g) = 19.171450 = 0.132

%age of Mg+ (g) = 0.02850.0417 × 100 = 68.35
and %age of Mg2+ (g) = 100 – 68.35 = 31.65

Question 3.
Which of the elements Na, Mg, Si, P would have the greatest difference between the first and the second ionization enthalpies. Briefly explain your answer

Answer:
Among Na, Mg, Si, P, Na is an alkali metal. It has only one electron in the valence shell. Therefore, its IE1 is low: However, after the removal of the first electron, it acquires a Neon gas configuration i.e., Na+ (1s2, 2s2p6). Therefore its IE2 is expected to be very high. Consequently, the difference in IE1 and IE2 comes to be greatest in the case of Na.

Question 4.
The IE2 of Mg is higher than that of Na. On the other hand, the IE2 of Na is much higher than that of Mg. Explain,

Answer:
The first electron in both cases has to be removed from the 3s orbital, but the nuclear charge of Na is less than that of Mg. After the removal of the first electron from Na, the electronic configuration of Na+ is 1s2, 2s2 2p6, i.e., that of noble gas which is very stable and the removal of the 2nd electron is very difficult. In the case of Mg after the removal of the first electron, the electronic configuration of Mg+ is 1s2, 2s2 2p6 3s. The 2nd electron to be removed is again from 3s orbital which is easier.

Question 5.
The amount of energy released when 1 × 1010 atoms of chlorine in vapor state are converted to Cl ions according to the equation.

Cl (g) + e → Cl (g) is 57.86 × 10-10 J
Calculate the electron gain enthalpy of the chlorine atom in terms of kJ mol-1 and eV pet atom.
Answer:
The electron gain enthalpy of chlorine

[Ar]3d10 4s2 is Zinc metal with At. no. = 30.

(iii) [Ar]3d10 4s2 4p6 5s2
Answer:
[Ar]3d10 4s2 4p6 5s2 is Strontium metal with At. no. = 38.

(iv) [Arl 3d10 4s2 4p6 5s1
Answer:
[Ar] 3d10 4s2 4p6, 5s1 is*Rubidium metal with At. no. = 37.

Alkali metals are the most metallic, followed by alkaline earth metals and transition metals. Among alkali metals – Rubidium (37) is the most metallic. Among alkaline earth metals (Ca, Sr) Sr (Strontium) is more metallic than Calcium (Ca) as the metallic character increases from top to bottom in a group. Zinc – the transition metal is the least metallic. Thus metallic character increases from
Zn < Ca < Sr < Rb or (ii) < (i) < (iii) < (iv)

Question 7.
The formulation of F (g) from F (g) is exothermic whereas that of O2- (g) from O (g) is endothermic. Explain.

Answer:
F (g) + e (g) → F (g); ΔH = Negative
Energy is released when an extra electron from outside is added to a neutral isolated gaseous atom of an element.
To convert, O (g) to O2- (g) two steps are required
(i) O (g) + e (g) → O (g); ΔH1 = – 141 kJ mol-1
(ii) O (g) + e (g) → O2- (g); ΔH2 = + 780 kJ mol-1

Hence the over all processes endothermic (+ 780 – 141 = + 639 kJ mol-1) whereas F (g) to F (g) is exothermic.

Question 8.
Explain the important general characteristics of groups in the modem periodic table in brief.

Answer:
The elements of a group show the following important similar characteristics.
(0 Electronic configuration. All elements in a particular group have similar outer electronic configuration e.g., all elements of group I’, i.e., alkali metals have ns1 configuration in their valency shell. Similarly, group 2 elements (alkaline Earths) haye ns2 outer configuration and halogens (group 17) have ns2 np5 configuration (where n is the outermost shell).

(it) Valency. The valency of an element depends upon the number of electrons in the outermost shell. So elements of a group show the same valency, e.g., elements of group 1 show + 1 valency and group 2 show + 2 valencies i.e. valency i.e., NaCl > MgCl2 etc.

(iii) Chemical properties. The chemical properties of the elements are related to the number of electrons in the outermost shell of their atoms. Hence all elements belonging to the same group show similar chemical properties. But the degree of reactivity varies gradually from top to bottom in a group. For example, in group 1 all the elements are highly reactive metals but the degree of reactivity increases from Li to Cs. Similarly, elements of group 17, i.e., halogens: F, Cl, Br, I are all non-metals and they’re- reactivity goes on decreasing from top to bottom.

Question 9.
Explain the electronic configuration in periods in the periodic table.

Answer:
Each successive period in the periodic table is associated with the filling Up of the next higher principal energy level (n – 1, n – 2, etc.). It can be readily seen that the number of elements in each period is twice the number of atomic orbitals available in the energy level that is being filled. The first period starts with the filling of the lowest level (1s) and has thus the two elements – hydrogen (1s1) and helium (1s2) when the first shell (K) is completed. The second period starts with lithium and the third electron enters the 2s orbital.

The next element, beryllium has four electrons and has the electronic configuration 1s2 2s2. Starting from the next element boron, the 2p orbitals are filled with electrons when the L shell is completed’ at neon (2s2 2p6). Thus there are 8 elements in the second period. The third period (n = 3) being at sodium, and the added electron enters a 3s orbital. Successive filling of 3s and 3p orbitals give rise to the third period of 8 elements from sodium to argon.

The fourth period (n = 4) starts at potassium with the filling up of 4p of 4s orbital. Before the 4p orbital is filled, the filling up of 3d orbitals becomes energetically favorable and we come across the so-called 3d transition series of elements. The fourth period ends at krypton with the filling up of the 4p orbitals. Altogether we have 18 elements in the fourth period. The fifth period (n = 5) beginning with rubidium is similar to the fourth period and contains the 4d transition series starting at yttrium (Z = 39).

This period ends at xenon with the filling up of the 5p orbitals. The sixth period (n = 6) contains 32 elements and successive electrons enter 6s, 4/, 5d, and 6p orbitals, in that order. Filling up of the 4/ orbitals being with cerium, (Z = 58) and ends at lutetium (Z = 71) to give the 4/-inner transition series which is called the lanthanide series. The seventh period (n = 7) is similar to the sixth period with the successive filling up of the 7s, 5f, 6d, and 7p orbitals and includes most of the man-made radioactive elements.

This period will end at the element with atomic number 118 which would belong to the noble gas family. Filling up of the 5f orbitals after actinium (Z = 89) gives the 5f-inner transition series known as the actinide series. The 4f and 5f transition series of elements are placed separately in the periodic table to maintain its structure and to preserve the principle of classification by keeping elements with similar properties in a single column.

Question 10.
Explain the variation of valence in the periodic table
.

Answer:
Variation of valence in a group as well as across a period in the periodic table occurs as follows:
1. In a group: All elements in a group show the same valency. For example, all alkali metals (group 1) show a valency of 1+. Alkaline earth metals (group 2) show a valency of 2+.

However, the heavier elements of p-block elements (except noble gases) show two valences: one equal to the number of valence electrons or 8-No. of valence electron# and the other two less. For example, thallium (Tl) belongs to group 13. It shows valence of 3+ and 1+.

Lead (Pb) belongs to group 14. If shows valance of 4+ and 2+.
Antimony (Sb) and Bismuth (Bi) belong to group 15. They show valence of 5+ and 3+ being more stable.

This happens due to the non-participation of tie two s-electrons present in the valence shell of these elements. This non-participation of one pair of s-electrons in bonding is called the inert-pair effect.

2. In a period: The number of the valence electrons increases – in going from left to right in a period of the periodic table. Therefore the valency of the elements in a period first increases, and then decreases.

NCERT MOST IMPORTANT QUESTIONS ON STRUCTURE OF ATOM

1.Which experiment led to the discovery of electrons and how?  

Ans:The cathode ray discharge tube experiment performed by J.J. Thomson led to the discovery of negatively charged particles called electron.

A cathode ray tube consists of two thin pieces of metals called electrodes sealed inside a glass tube with sealed ends. The glass tube is attached to a vacuum pump and the pressure inside the tube is reduced to 0.01mm. When fairly high voltage (10, 000V) is applied across the electrodes, invisible rays are emitted from the cathode called cathode rays. Analysis of this rays led to the discovery electrons.


2.Give the main properties of canal ray experiment.

Ans:The canal ray experiment led to the discovery of –

(i)The anode rays, travel in straight line

(ii)They are positively charged as they get deflected towards the –ve end when subjected to an electric and magnetic field.

(iii)They depend upon the nature of gas present in the cathode tube.

(iv)The charge to mass ration (e/m) of the particle is found to depend on the gas from which they originate.

NCERT MOST IMPORTANT QUESTIONS CLASS – 11 | CHEMISTRY IMPORTANT QUESTIONS PART-1 | CHAPTER -1 | SOME BASIC CONCEPTS OF CHEMISTRY | EDUGROWN |

In This Post we are  providing Chapter-1 SOME BASIC CONCEPTS OF CHEMISTRY NCERT MOST IMPORTANT QUESTIONS for Class 11 CHEMISTRY which will be beneficial for students. These solutions are updated according to 2021-22 syllabus. These MCQS  can be really helpful in the preparation of Board exams and will provide you with a brief knowledge of the chapter.

NCERT MOST IMPORTANT QUESTIONS ON SOME BASIC CONCEPTS OF CHEMISTRY

Question 1.
Define Mole. What is its numerical value?

Answer:
A mole is the amount of a substance that contains as many entities (atoms, molecules, or other particles) as there are atoms in exactly 0.012 kg or 12 g of the carbon-12 isotope.

Its numerical value is 6.023 × 1023.

Question 2.
Define molarity. Is it affected by a change in temperature?

Answer:
The molarity of a solution is defined as the number of moles of the solute present per liter of the solution. It is represented by the symbol M. Its value changes with the change in temperature.

Question 3.
What do you mean by Precision and accuracy?

Answer:
Precision and accuracy: The term precision refers to the closeness of the set of values obtained from identical measurements of a quantity.

Accuracy refers to the closeness of a single measurement to its true value.

Question 4.
Distinguish between fundamental and the derived units.

Answer:
Fundamental units: Fundamental units are those units by which other physical units can be derived. These are mass (M), Length (L), time (T), temperature (°).

Derived units: The units which are obtained by the combination of the fundamental units are called derived units.

Question 5.
Define molality and write its temperature dependence.

Answer:
Molality is defined as the number of g moles of the solute dissolved per kilogram of the solvent.
Molality (m) =  Mole of solute  Mass of the solvent in kg

The molality of the solution does not depend upon the temperature.

Question 6.
Two containers of equal capacity A1 and A2 contain 10 g of oxygen (O2) and ozone (O3) respectively. Which of the two will have greater no. of O-atoms and which will give greater no. of molecules?

Answer:
10 g of O2 = 1032 mol = 1032 × 6.02 × 1023 molecules
= 1.88 × 1023 molecules
= 3.76 × 1023 atoms.

10 g of O2 = 1048 mole = 1048 × 6.02 × 1023 molecules
= 1.254 × 1023 molecules
= 3.76 × 1023 atoms

Thus both A1 and A2 contain the same no. of atoms, but A1 contains more numbers of molecules.

Question 7.
Assuming the density of water to be 1 g/cm3,
calculate the volume occupied by one molecule of water.

Answer:
1 Mole of H2O = 18 g = 18 cm3[∵ density of H2O = 1 g/cm3]
= 6.022 × 1023 molecules of H2O
1 Molecule will have a volume
= 186.022×1023 cm- = 2.989 × 10-23 cm3.

Question 8.
State the law of Multiple Proportions. Explain with two examples
.

Answer:
The Law of Multiple Proportions states:
“When two elements combine to form two or more than two chemical compounds than the weights of one of elements which combine with a fixed weight of the other, bear a simple ratio to one another.

Examples:
1. Compound of Carbon and Oxygen: C and O combine to form two compounds CO and CO2.
In CO2 12 parts of wt. of C combined with 16 parts by wt. O.
In CO2 12 parts of wt. of C combined with 32 parts by wt. of O.
If the weight of C is fixed at 12 parts by wt. then the ratio in the weights of oxygen which combine with the fixed wt. of C (= 12) is 16: 32 or 1: 2.
Thus the weight of oxygen bears a simple ratio of 1: 2 to each other.

2. Compounds of Sulphate (S) and Oxygen (O):
S forms two oxides with O, viz., SO2 and SO3
In SO2, 32 parts of wt. of S combine with 32 parts by wt. of O.
In SO3, 32 parts of wt. of S combine with 48 parts by wt. of O.
If the wt. of S is fixed at 32 parts, then’ the ratio in the weights of oxygen which combine with the fixed wt. of S is 32: 48 or 2: 3.

Thus the weights of oxygen bear a simple ratio of 2: 3 to each other.

Question 9.
State the law of Constant Composition. Illustrate with two examples
.

Answer:
Law of Constant Composition of Definite Proportions states: “A chemical compound is always found, to be made up of the same elements combined together in the same fixed proportion by weight”.

Examples:

1. CO2 may be prepared in the laboratory as follows:
Some Basic Concepts of Chemistry Class 11 Important Extra Questions Chemistry 2
In all the above examples, CO2 is made up of the same elements i. e., Carbon (C) and Oxygen (O) combined together in the same fixed proportion by weight of 12: 32 or 3: 8 by weight.

Question 10.
Define empirical formula and molecular formula. How will you establish a relationship between the two? Give examples.

Answer:
The empirical formula of a compound expresses the simplest whole-number ratio of the atoms of the various elements present in one molecule of the compound.

For example, the empirical formula of benzene is CH and that of glucose is CH2O. This suggests that in the molecule of benzene one atom of Carbon (C) is present for every atom of Hydrogen (H). Similarly in the molecule of glucose (CH2O), for every one atom of C, there are two atoms of H and one atom of O present in its molecule. Thus, the empirical formula of a compound represents only the atomic ratio of various elements present in its molecule.

The molecular formula of a compound represents the true formula of its molecule. It expresses the actual number of atoms of various elements present in one molecule of a compound. For example, the molecular formula of benzene is C6H6 and that of glucose is C6H12O6. This suggests that in one molecule of benzene, six atoms of C and 6 atoms of H are present. Similarly, one molecule of glucose (C6H12O6) actually contains 6 atoms of C, 12 atoms of H, and 6 atoms of O.

Relation between the empirical and molecular formula
Molecular formula = n × Empirical formula where n is an integer such as 1, 2, 3…
When n = 1; Molecular formula = Empirical formula
When n = 2; Molecular formula = 2 × Empirical formula.
The value of n can be obtained from the relation.
n =  Molecular mass  Empirical formula mass 

The molecular mass of a volatile substance can be determined by Victor Meyer’s method or by employing the relation.
Molecular mass = 2 × vapour density .

Empirical formula mass can however be obtained from its empirical formula simply by adding the atomic masses of the various atoms present in it.

Thus the empirical formula mass of glucose CH20
= 1 × 12 + 2 × 1 + 1 × 16 = 30.0 u.

NCERT MOST IMPORTANT QUESTIONS CLASS – 11 | PHYSICS IMPORTANT QUESTIONS | CHAPTER -15 | WAVES | EDUGROWN |

In This Post we are  providing Chapter-15 WAVES NCERT MOST IMPORTANT QUESTIONS for Class 11 PHYSICS which will be beneficial for students. These solutions are updated according to 2021-22 syllabus. These MCQS  can be really helpful in the preparation of Board exams and will provide you with a brief knowledge of the chapter.

NCERT MOST IMPORTANT QUESTIONS ON WAVES

Question 1.
A sitar wife and a tabla when sounded together give 4 beats/ sec. What do we conclude from this? As the tabla membrane is tightened, the beat rate increases or decreases, explain.

Answer:
When sitar and tabla are sounded together, they give 4 seats/ sec. From this, we conclude that the frequencies of the two sounds differ by 4. If the frequency of tabla is greater than that of a sitar, then on tightening the tabla membrane, the frequency of tabla will further increase and hence the difference in frequencies will increase.

Thus beat rate will increase. If the frequency of tabla is less than that of sitar, then on tightening the tabla membrane, the frequency of tabla will increase and the difference in frequencies will decrease. So beat rate will decrease.

Question 2.
When we start filling an empty bucket with water, the pitch of sound produced goes on changing. Why?

Answer:
An empty bucket behaves as a closed organ pipe. The frequency of fundamental note produced by it is given by
v = v4l.

As the bucket starts filling, the length (l) of the resonating air column decreases, and hence frequency increases. Since the pitch of a sound depends upon the frequency. So it changes with the change in frequency.

Question 3.
Two loud-speakers have been installed in an open space to listen to a speech. When both are operational, a listener sitting at a .particular- place receives a very faint sound. Why? What
will happen if one loud-speaker is kept off?

Answer:
When the distance between two loud-speakers from the position of listener is an odd multiple of λ2, then due to destructive interference between sound waves from two loud-speakers, a feeble sound is heard by the listener.

When one loud-speaker is kept off, no interference will take place and the listener will hear the full sound of the operating loud-speaker.

Question 4.
Distinguish between progressive waves and stationary waves.

Answer:
Progressive waves:

  1. The disturbance travels onward. It is1 handed over from one particle to the next.
  2. Energy is transported in the medium along with the propagation of waves.
  3. Each particle of the medium executes S.H.M. with the same amplitude.
  4. No particle of the medium is permanently at rest.
  5. Changes in pressure and density are the same at all points of the medium.

Stationary waves:

  1. The disturbance is confined to a particular region and there is no onward motion.
  2. No energy is transported in the medium.
  3. All the particles of the medium except at nodes execute S.H.M. with different amplitude.
  4. The particles of the medium at nodes are at rest.
  5. The changes of pressure and density are maximum at nodes and minimum at antinodes.

Question 5.
Distinguish between musical sound and noise.

Answer:
Musical sound:

  1. It produces a pleasant effect on the ear.
  2. It has a high frequency.
  3. There are no sudden changes in the amplitude of the musical sound waves.
  4. It is a desirable sound.

Noise:

  1. It produces an unpleasant effect on the ear.
  2. It has a low frequency.
  3. There are sudden changes in the amplitude of noise waves.
  4. It is an undesirable sound.

Question 6.
What are the characteristics of wave motion?

Answer:

  1. Wave motion is a form of disturbance that travels in a medium due to repeated periodic motion of the particles of the medium.
  2. The wave velocity is different from the particle velocity.
  3. The vibrating particles of the medium possess both K.E. and P.E.
  4. The particle velocity is different at different positions of its vibrations whereas wave velocity is constant throughout a given medium.
  5. Waves can undergo reflection, refraction, diffraction, dispersion, and interference.

Question 7.
Show that for 1°C change in temperature, the velocity of sound changes by 0.61 ms-1.

Answer:
We know that v ∝ T−−√ .
If vt and vo be the velocity of sound at T°C and 0°C respectively,
Class 11 Physics Important Questions Chapter 15 Waves 5
where α = vt−v0t is called temp. coefficient of the velocity of sound.

Putting vo = 332 ms-1 at T0 i.e. 0°C, we get
α = 332546 = 0.61 ms-1 °C-1

Question 8.
An electric bell is put in an evacuated room (a) near the center (b) close to the glass window, in which case the sound is heard (i) inside the room, (ii) out of the room.

Answer:

  1. Sound is not heard in cases (a) and (b) inside the room as the medium is not there for the propagation of sound.
  2. In case (a) sound cannot be heard outside for the reason given in (i) above.

In case (b) since the bell is very close to the window, the glass pane picks up its vibrations which are conveyed to the eardrum through the air outside the room. So, the sound can be heard in condition (b).

Question 9.
A progressive wave is given by
y = 12 sin (5t – 4x)
On this wave, how far away are the two points having a phase difference of π2?

Answer:
Here, ΔΦ = phase difference = π2

Let Δx be the corresponding path difference,
Class 11 Physics Important Questions Chapter 15 Waves 36

Question 10.
The figure here shows the wave, y = A sin (ωt – kx) at any instant traveling in the +x direction. What is the slope of the curve at
B?
Class 11 Physics Important Questions Chapter 15 Waves 37

Answer:
Here, the particle velocity is maximum at B and is given by
vo = ωA.
Also, wave velocity is given by
C = ωk
∴ So the slope v0C=ωAω/k = kA

Question 25.
Two sound waves
y1 = A1 sin 1000 π(t – x220 )
and y2 = A2 sin 1010 π(t – x220 ) are superposed. What is the frequency with which the amplitude varies?
Answer:
Rate of variation of amplitude is equal to the beat frequency.
Here, 2πν1 = 1000 π
or
ν1 = 500
and 2πν2 = 1010 π
or
ν2 = 505

∴ beat frequency = ν2 – ν1
= 505 – 500
= 5.
