  2. Bmethyl amine
  3. Cdimethyl amine
  4. D2-amino propane

Correct answer

C. dimethyl amine

Step-by-step solution

Only aliphatic primary amines react with nitrous acid to give alcohols with the evolution of N₂ gas. R- NH ₂+ HONO 273-278 ~K R- OH + N ₂+ H ₂ O Dimethyl amine is a secondary amine, it will not give N ₂ gas.
