Question

A primary amine is formed an amide by the treatment of
bromine and alkali. The primary amine has :
(a) 1 carbon atom less than amide
(b) 1 carbon atom more than amide
(c) 1 hydrogen atom less than amide
(d) 1 hydrogen atom more than amide

Answer 1

Explanation:

(b) 1 carbon atom more than amide is the correct answer

Answer 2

A primary amine is formed from an amide by the treatment of bromine and alkali. The primary amine has one carbon less than amide.

Option: (a)

Explanation:

• When a primary amine is formed reaction of alkali and bromine there is decrease in the number of carbon which is originally present in the amide.

• This is because the primary amine undergoes hofmann degradation of the amine reaction. In this reaction from the amide the CO group is lost.

• Due to this there is a loss of a carbon atom. Bromine and strong alkali is a must for hofmann degradation reaction of the amines.
