Question

Give a simple chemical test to distinguish between Aniline and N, N-dimethylaniline

Solution 1

Aniline is a primary amine while N, N-dimethylaniline is a tertiary amine. They both can be distinguished by Carbylamine test. Primary amines on heating with chloroform and ethanolic potassium hydroxide, form foul-smelling isocyanides or carbylamines. Aniline, being an aromatic primary amine gives positive carbylamine test. However, N, N-dimethylaniline being a tertiary amine does not. 

Solution 2

Carbylamine test can be used to distinguish.
