MHT CET 2026 Chemistry question

Identify the product B' in the following reaction

(A)
(B)
(C)Correct
(D)

Answer: (C)

Solution

Step 1: methyl iodide undergoes nucleophilic substitution with KCN (which gives alkyl cyanides): CH_3I + KCN \to CH_3CN + KI, so A is methyl cyanide (acetonitrile). Step 2: Na in ethanol (nascent hydrogen, Mendius reduction) reduces the cyanide group to a primary amine: ${≡}N + 4[H]
