Question

Aromatic primary amines can be distinguished from aliphatic primary amines by (A) Tollen's test. (B) action on red litmus paper. (C) Azo dye test. (D) action with diluted HCl .

Tardigrade Admin · Accepted Answer

Aromatic primary amines can be distinguished from aliphatic primary amines by the azo dye test. When aromatic amines react with nitrous acid in the presence of

N a N O_{2} / H Cl

at a very lower temperature, diazonium salt is formed, which is not possible in the case of aliphatic primary amines.
