Sia ? 6 years, 7 months ago

The merits of Green Revolution were :

After launching this revolution, India achieved self-sufficiency in food production. Poor farmers also get benefit from this revolution.
It raised the availability of food in the country with agricultural growth mainly a rise in wheat and rice production.
Some regions like Punjab, Haryana and Western Uttar Pradesh became agriculturally prosperous, flourished more and hence the living standards also improved. Thus, first socially, then politically and economically the status of farmers in these states rose.

Why carboxylic acid is more acidic than phenol and alcohol

Posted by Sakshi Kaur ? 6 years, 7 months ago

CBSE > Class 12 > Chemistry

2 answers

Khuskaran Sidhu 6 years, 7 months ago

Because of resonance stability of carboxylate ion

1Thank You

Yogita Ingle 6 years, 7 months ago

Carboxylic acids are acidic due to resonance stabilization of carboxylate anion and in phenols, acidic character is present due to resonance stabilization of phenoxide anion. Carboxylic acid are more acidic than phenols because the negative charge in carboxylate anion is more spread out as compared to the phenoxide ion as there are two electronegative O-atoms in carboxylate anion in comparison to one in phenoxide ion. In the resosnce structures of carboxylate anion, the negative charge is present on the O-atoms while in resonance of phenoxide ion negative charge is also present on electropositive carbon atom, which leads to less stability of phenoxide ion than carboxylate anion.

Why all producers good are not capital good?

Posted by Wansara Ryngksai 6 years, 7 months ago

CBSE > Class 12 > Economics

1 answers

Yogita Ingle 6 years, 7 months ago

All producer goods are not capital goods, because producer goods includes:
(i) Goods which are used as raw material like wood, used to make furniture.
(ii) Goods which are used as fixed assets like plant and machinery.
Capital goods include only fixed assets of the producers. These are durable goods. On the other hand, goods used as raw material are not capital goods as these are not repeatedly used in the process of production. Thus, all producers goods are not capital goods.

background of chandragupt maurya

Posted by Nikita Singh 6 years, 7 months ago

CBSE > Class 12 > History

1 answers

Gaurav Seth 6 years, 7 months ago

Chandragupta Maurya was born sometime around 340 BCE, reportedly in Patna, now in the Bihar state of India.

<hr />

He was of humble origin, since nobody recorded anything about him until he founded the Mauryan Empire.

<hr />

Chandragupta was brave and charismatic – a born leader.

<hr />

The young man came to the attention of a famous Brahmin scholar, Chanakya, who began to groom Chandragupta helping him raise an army, and taught him tactics through different Hindu sutras.

<hr />

Chandragupta’s new empire, at the time of it's founding, stretched from what is now Afghanistan in the west to Myanmar (Burma) in the west, and from Jammu/Kashmir in the north to the Deccan Plateau in the south. Chanakya served as the equivalent of a “prime minister” in the fledgling government.

<hr />

When Alexander the Great died in 323 BCE, his generals divided up his empire so that each of them would have a territory to rule. By about 316, Chandragupta Maurya was able to defeat and incorporate all the ones in the mountains of Central Asia, extending his empire to the edge of what is now Iran, Tajikistan and Kyrgyzstan.

<hr />

By the end of his reign, Chandragupta Maurya had unified almost all of the Indian subcontinent under his rule. His grandson, Ashoka, would go on to add Kalinga and the Tamils to the empire, as well.

<hr />

Chandragupta became fascinated with Jainism, an extremely ascetic belief system.

<hr />

In 298 BCE, the emperor renounced his rule, handing over power to his son Bindusara. Chandragupta traveled south to a cave at Shravanabelogola, now in Karntaka. There he meditated without eating or drinking for five weeks, until he died of starvation.

<hr />

Chandragupta is remembered as the unifier of India and was the first king to be depicted on an Indian Postage Stamp.
