MHT CET Chemistry Question (2026) — Solution

Question

Identify the product obtained when RCN is treated with sodium and alcohol.

Options

  1. A. RCONH _2
  2. B. RCOONH _4
  3. C. RCH _2 NH _2
  4. D. R ( CH _2)_3 NH _2

Answer

C. RCH _2 NH _2

Step-by-step solution

The reduction of alkyl cyanides (nitriles) with sodium and alcohol is known as the Mendius reduction. In this reaction, the cyano group (- C N ) is reduced to a primary amine group (- CH _2 NH _2). R-C N + 4[ H ] Na/C _2 H _5 OH R-CH _2 -NH _2 The product obtained is a primary amine, RCH _2 NH _2. Answer: RCH _2 NH _2
