JEE Main 2026 Chemistry question
Benzyl isocyanide can be obtained from: A. PhCH₂Br + AgCN. B. PhCH₂NH₂ + CHCl₃/aq. NaOH. C. PhBr + AgCN. D. PhNH₂ + CHCl₃/aq. NaOH. E. PhCH₂CH₂Br + KCN.
Answer: (A)
Solution
AgCN with an alkyl (benzylic) halide gives the isocyanide (A). The carbylamine reaction of the primary amine benzylamine with CHCl₃/NaOH also gives benzyl isocyanide (B).
