Vedclass · Answer

(D) Acidic hydrolysis of alkyl cyanides $(R-CN)$ yields carboxylic acids and ammonium salts. However,the question asks for a primary amine. Let us re-evaluate the options:$1$. $CH_3CN$ (Acetonitrile) on complete hydrolysis gives $CH_3COOH$ and $NH_4^+$.$2$. $CH_3NC$ (Methyl isocyanide) on acidic hydrolysis gives $CH_3NH_2$ (Methylamine) and $HCOOH$ (Formic acid).Reaction: $CH_3NC + 2H_2O \xrightarrow{H^+} CH_3NH_2 + HCOOH$.Therefore,$CH_3NC$ is the correct answer.
