Question

Benzyl isocyanide can be obtained by:

Choose the correct answer from the options given below:

• A. A and D
• B. Only B
• C. B and C
• D. A and B

Hint:

For the preparation of isocyanides, halogen-substituted alkyl groups often react with cyanide (CN) or other nucleophiles. In these cases, nucleophilic substitution mechanisms such as SN₂ are involved.

Answer 1

The Correct Option is D

Benzyl isocyanide is obtained via the reaction of a benzyl halide with an appropriate nucleophile. Here are the reactions:
- In (A), the reaction of CH₂Br with AgCN leads to the formation of benzyl isocyanide.
- In (B), the reaction of CH₂NH₂CHCl₂ with aqueous KOH gives the corresponding isocyanide after substitution of the chloro group with CN.
Thus, the correct answer is (A) and (B).
