NEET Chemistry (general) Assertion Reason Question
Assertion (A): Aldehydes can be prepared by the reduction of nitriles using stannous chloride in the presence of hydrochloric acid.
Reason (R): The reduction of nitriles using stannous chloride followed by hydrolysis is called the Rosenmund reduction.
Both (A) and (R) are true, and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false.
Correct Answer
Detailed Explanation
The assertion is true as nitriles can be reduced to aldehydes using stannous chloride in the presence of hydrochloric acid, known as the Stephen reaction. However, the reason is false because the Rosenmund reduction involves the hydrogenation of acyl chlorides using palladium on barium sulfate.
