One chemical test to distinguish between methylamine and dimethylamine

Asked by admin @ in Science viewed by 378 People

Give one chemical test to distinguish between the following pairs of compounds: (i) methylamine and dimethylamine. (ii) aniline and benzylamine

Answered by admin @


Methylamine and dimethylamine can be distinguished by the carbylamine test.

Carbylamine test: Aliphatic and aromatic primary amines on heating with chloroform and ethanolic potassium hydroxide form foul-smelling isocyanides or carbylamines. Methylamine (being an aliphatic primary amine) gives a positive carbylamine test, but dimethylamine does not.


Aniline and benzylamine can be distinguished by their reactions with the help of nitrous acid, which is prepared in situ from a mineral acid and sodium nitrite. Benzylamine reacts with nitrous acid to form unstable diazonium salt, which in turn gives alcohol with the evolution of nitrogen gas.
