Question

Reaction of nitrus acid on primary aliphatic amines

Answer 1

Answer:

nitrus acid when reacts with aliphatic primary amine form primary alcohol and nitrogen gas is evolved.

Answer 2

the list of reactions of Nitrous acid on primary amines:

• Nitrous acid reacts with the aliphatic amines and gives a test to distinguish primary, secondary and tertiary amines.
• on reaction with primary amines, Nitrogen gas is evolved.
• On reaction with secondary amines, oily N-Nitrosamine is seen.
• On reaction with tertiary amines, an ammonium compound is obtained which is a clear solution.
• Nitrous acid is actually a Bronsted acid, which under acidic condition reacts with amines to get reversible salt.
• Depending on the behavior of the cation(NO+), reaction of Nitrous acid with the primary aliphatic amine can be explained.
