Question

Which of the following compound will be formed as major product when ethyl chloride reacts with $AgCN$ ?

• A. Ethylcyanide
• B. Both (a) and (b) will be formed in same quantities
• C. Ethylisocyanide
• D. Acetonitrile

Answer 1

The correct option is C Ethylisocyanide

$AgCN$ is predominantly covalent. Although C site is more nucleophilic than N site but not available in case of $AgCN$. Hence, lone pair of N attacks the ethyl chloride and isocyanide is formed as the major product.​ Hence, the major product will be ethylisocyanide.
