The correct statement regarding a carbonyl compound with hydrogen atom on its alpha carbon is :
A. A carbonyl compound with hydrogen atom on its a-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
B. A carbonyl compound with hydrogen atom on its a-carbon rapidly equilibrates with its corresponding enol and this process is known as keto enol tautomerism.
C. A carbonyl compound with hydrogen atom on its a-carbon never equilibrates with corresponding enol.
D. A carbonyl compound with hydrogen atom on its a-carbon rapidly equilibrates with its corresponding enol and this process is known as aldehyde-ketone equilibration.

Read the passage carefully and answer the Questions:
Amines are classified as primary \(\left(1^{\circ}\right)\), secondary \(\left(2^{\circ}\right)\) and tertiary \(\left(3^{\circ}\right)\) depending upon the number of hydrogen atoms replaced by alkyl or aryl groups in ammonia molecules. Aliphatic amines are a stronger bases due to \(+I\) effect of an alkyl groups. Intermolecular hydrogen bonding in primary and secondary amines affects the boiling points of amines. The intermolecular association is more in primary amines than in secondary amines as there are more number of hydrogen atoms available for hydrogen bond formation. Nitro compounds are reduced to amines by passing hydrogen gas in the presence of finely divided nickel, palladium or platinum and also by reduction with metals in an acidic medium. Gabriel synthesis is used for the preparation of primary amines. Primary amines react with nitrous acid to give unstable diazonium-salts which can be used to synthesize a variety of compounds.

Which among the following is the strongest base in aqueous solution?

Answer the question on the basis of passage given below :
Living systems are made up of various complex bio-molecules like carbohydrates, proteins, nucleic acids, lipids etc. Proteins and carbohydrates are essential constituents of our food. Carbohydrates are primarily produced by plants and form a very large group of naturally occurring organic compounds. Some common examples are cane sugar, glucose, starch etc.
Which of the following is a structural component of starch?

Read the paragraph given below and answer the question. Insulin used for diabetes was earlier extracted from slaughtered cattle and pigs. Insulin from an animal source, though caused some patients to develop allergy or other type of reactions. Insulin consists of two short polypeptide chains: chain A and chain B, that are linked bridges. In mammals, including human, insulin is synthesised as a pro-hormone. Patient with diabetes have:
