Question

Identify compound ‘B’ in following series of reactions?

• A. Nitroethane
• B. Ethyl chloride
• C. Ethyl alcohol
• D. Ethyl amine

Hint:

The reaction of acetonitrile with Na and alcohol forms ethyl amine, which further reacts with NaNO₂/dil. HCl to form ethyl alcohol.

Answer 1

The Correct Option is C

Step 1: Analyzing the reactions.
Acetonitrile reacts with Na/Alcohol to form a product A (which is ethyl amine, formed by reduction). The product A then reacts with NaNO₂ and dilute HCl to form compound B, which is ethyl alcohol.

Step 2: Analyzing the options.
(A) Nitroethane: This is not the correct product in this sequence of reactions.
(B) Ethyl chloride: This is not the correct product.
(C) Ethyl alcohol: Correct — This is the correct product B after the reaction.
(D) Ethyl amine: This is formed after the first step, but compound B is ethyl alcohol.

Step 3: Conclusion.
The correct answer is (C) Ethyl alcohol.
