MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The reaction of methyl bromide ( CH _3 Br ) with potassium cyanide ( KCN ) is a nucleophilic substitution reaction which yields ethanenitrile ( CH _3 CN ) as the major product A. CH _3 Br + KCN CH _3 CN + KBr The reduction of ethanenitrile ( CH _3 CN ) with sodium and ethanol ( Na / C _2 H _5 OH ) is known as the Mendius reduction. It reduces the nitrile group to a primary amine, yielding ethanamine ( CH _3 CH _2 NH _2) as product B. CH _3 CN + 4[ H ] Na / C _2 H _5 OH CH _3 CH _2 NH _2 Answer: Ethanamine
