Question

An aqueous solution of sodium nitrite on boiling with \( \alpha \)-chlorosodium propionate gives

• A. 1-Nitropropane
• B. Nitroethane
• C. 2-Nitropropane
• D. Nitromethane

Hint:

In reactions involving nitro group substitution, the reaction conditions (such as boiling with sodium nitrite) help determine the final product.

Answer 1

The Correct Option is B

Step 1: Understanding the reaction.
The reaction involves the substitution of a chlorine atom with a nitro group in the molecule, and this happens with an alpha-chlorosodium propionate. Upon boiling, sodium nitrite reacts with the alpha-chlorosodium propionate to give Nitroethane.
Step 2: Analyzing the options.
(A) 1-Nitropropane: Incorrect, this would involve a different substitution pattern.
(B) Nitroethane: Correct — This is the product when sodium nitrite reacts with \( \alpha \)-chlorosodium propionate.
(C) 2-Nitropropane: Incorrect, as the nitro group would be attached to the first carbon.
(D) Nitromethane: Incorrect, as this is not the correct product for the reaction.
Step 3: Conclusion.
The correct answer is (B) Nitroethane.
