NEET Chemistry Nucleophilic Addition Assertion Reason Question
Assertion (A): Aldehydes react with hydrogen cyanide (HCN) more readily than ketones.
Reason (R): Aldehydes have less steric hindrance around the carbonyl carbon compared to ketones, facilitating nucleophilic attack.
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
According to the NCERT context, aldehydes and ketones react with HCN, but aldehydes react more readily due to less steric hindrance, which allows easier nucleophilic attack.
