Question

Benzyl isocyanide can be obtained by : Choose the correct answer from the options given below :

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

Answer 1

The Correct Option is C

Benzyl isocyanide is an organic compound, and its synthesis can be achieved through reactions that form isocyanide groups. Let's analyze each option:

1. Option (A): Reaction of benzyl bromide (\(C_6H_5CH_2Br\)) with silver cyanide (AgCN). This reaction typically forms benzyl isocyanide because AgCN can lead to the formation of isonitriles (isocyanides):

1. Option (B): Reaction of benzyl amine with chloroform in the presence of aqueous KOH is known as the carbylamine reaction. It produces isocyanides (isocyanides) as the main product: \(C_6H_5CH_2NH_2 + CHCl_3 + 3KOH \rightarrow C_6H_5CH_2NC + 3KCl + 3H_2O\)

Given these observations, options (A) and (B) are correct for the preparation of benzyl isocyanide. Therefore, the correct answer is A and B.
