Question

Write one chemical test to distinguish between methylamine and dimethylamine

Answer 1

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.
