Which of the following amines will not give $N_{2}$ gas on treatment with nitrous acid $(NaNO_{2} +$ $HCl)$ ?

Options:

Answer:

Solution:

All aliphatic primary amines liberate $N_{2}$ gas on treatment with $HNO_{2}$ . $R - NH_{2} + HONO ⟶ 273 - 278 K R - OH + N_{2} + H_{2} O$ Since no other class of amines liberate $N_{2}$ gas on treatment with $HNO_{2}$ , this reaction is used as a test for aliphatic primary amines.
