MHT CET 2026 Chemistry question
Aniline on treatment with / HCl at about gives a compound A, which on further treatment with CuCN / KCN gives a compound B, which when reacts with / Ni gives a compound C. The compound C on reaction with HNO2 gives a compound D. The structure of D is:
Answer: (A)
Solution
Step 1: aniline + /HCl at 0-5 C gives benzenediazonium chloride, (A). Step 2: CuCN/KCN (Sandmeyer reaction) gives benzonitrile, (B). Step 3: /Ni reduces the nitrile to benzylamine, (C).
