JEE Main Chemistry question

Chemistry Amines JEE Main

Aniline, in a set of reactions, yielded a product D: PhNH₂ —NaNO₂/HCl→ A —CuCN→ B —H₂/Ni→ C —HNO₂→ D. The structure of D would be

(A)C₆H₅NHCH₂CH₃
(B)C₆H₅CH₂OHCorrect
(C)C₆H₅CH₂NH₂
(D)C₆H₅NHOH

Answer: (B)

Solution

Diazotisation of aniline gives the diazonium salt A; the Sandmeyer reaction with CuCN replaces N₂⁺ with –CN, giving benzonitrile B; catalytic hydrogenation (H₂/Ni) reduces the nitrile to the primary
