MHT CET Chemistry Question (2026) — Solution

Question

Identify the product 'B' in the following reaction CH _3 - I KCN A Na/C _2 H _5 OH B

Options

  1. A. CH _3 -CH _2 -CN
  2. B. CH _3 -CH _2 -CH _3
  3. C. CH _3 -CH _2 -NH _2
  4. D. CH _3 -NH-C _2 H _5

Answer

C. CH _3 -CH _2 -NH _2

Step-by-step solution

Methyl iodide reacts with potassium cyanide to undergo nucleophilic substitution, forming methyl cyanide (acetonitrile) as product A. CH _3 I + KCN CH _3 CN (A) + KI Methyl cyanide undergoes Mendius reduction in the presence of sodium and ethanol to form ethylamine as product B. CH _3 CN + 4[ H ] Na/C _2 H _5 OH CH _3 CH _2 NH _2 (B) Thus, product B is CH _3 -CH _2 -NH _2. Answer: CH _3 -CH _2 -NH _2
