Question

Consider the sequence: Methyl chloride ($CH_3Cl$) is heated with $KCN$ to yield X. X undergoes total reduction with $LiAlH_4$ to yield Y. Y is treated with a cold mixture of $NaNO_2$ and $HCl$ to yield Z. Identify Z.

Answer: B

💡 Solution & Explanation

$CH_3Cl + KCN \rightarrow CH_3CN$ (X). Reduction of X with $LiAlH_4 \rightarrow CH_3CH_2NH_2$ (Y, Ethanmamine). Primary aliphatic amines react with $HNO_2$ to form unstable diazonium salts that rapidly collapse into carbocations, catching water to yield ethyl alcohol (Z).
