Reaction of propanamide with produces :
  1. (A)Ethylnitrile
  2. (B)Propylamine
  3. (C)Propanenitrile
  4. (D)Ethylamine✓ Correct

Answer: (D)

Solution

Treating an amide with bromine and alkali is the Hofmann bromamide degradation, in which the carbonyl carbon is lost and the group attached to it migrates to nitrogen, so the product is a primary amine having one carbon fewer than the amide. Propanamide, with three carbons, is thereby converted into a two-carbon primary amine, ethylamine.
