प्रश्न
Give a simple chemical test to distinguish between Aniline and N, N-dimethylaniline
Advertisements
उत्तर १
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.
उत्तर २
Carbylamine test can be used to distinguish.

A primary amine, \[\ce{RNH2}\] can be reacted with \[\ce{CH3-X}\] to get secondary amine, \[\ce{R-NHCH3}\] but the only disadvantage is that 3° amine and quaternary ammonium salts are also obtained as side products. Can you suggest a method where \[\ce{RNH2}\] forms only 2° amine?
