Question

Chemical test to distinguish between methyl amine and dim ethyl amine​

Answer 1

Explanation:

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.

Answer 2

Answer:

The best test for distinguishing methyl amine and dimethylamine is the Carbylamines test.

Carbylamine Test: Aliphatic and aromatic primary amines on heating with chloroform and ethanolic potassium hydroxide form foul-smelling isocyanides or carbylamines.

In this case, Methylamine (which is an aliphatic primary amine) gives a positive carbylamine test while dimethylamine wont.
