JEE MAIN Chemistry QUESTION #1019
Question 1
Match the compounds (List-I) with appropriate catalysts/reagents (List-II) for reduction to amines. (A) \(R\text{-CO-NH}_2\) (amide) (B) Nitrobenzene (C) \(R\text{-C}{\equiv}\text{N}\) (nitrile) (D) Imide (\(N\)-substituted cyclic imide). Reagents: (I) NaOH(aq) (II) \(\text{H}_2\)/Ni (III) \(\text{LiAlH}_4, \text{H}_2\text{O}\) (IV) Sn, HCl
  • (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
  • (A)-(III), (B)-(II), (C)-(IV), (D)-(I)
  • (A)-(II), (B)-(IV), (C)-(III), (D)-(I)
  • (A)-(III), (B)-(IV), (C)-(II), (D)-(I)✔️
Correct Answer Explanation
Amide (A) reduced by \(\text{LiAlH}_4\) (III). Nitrobenzene (B) reduced by Sn/HCl (IV) — classic reduction. Nitrile (C) reduced by \(\text{H}_2/\text{Ni}\) (II). Cyclic imide (D) — Hofmann-like with NaOH(aq) (I). Matching: A-III, B-IV, C-II, D-I.
