Question

Ketones and aldehydes react with ammonia (NH₃) or primary amines to form?

1) Alcohols
2) Carboxylic acids
3) Esters
4) Imines

Answer 1

Ketones and aldehydes react with ammonia or primary amines to form imines.

Step-by-step explanation:

When ketones and aldehydes react with ammonia or primary amines, the formation of imines occurs. Imines are compounds that have a carbon-nitrogen double bond (C=N).

This reaction is known as imine formation and is an important synthetic method in organic chemistry.
