NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): Aldehydes are generally more reactive than ketones in nucleophilic addition reactions.
Reason (R): The carbonyl carbon in aldehydes is less sterically hindered and has a greater partial positive charge compared to ketones.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
Aldehydes are more reactive than ketones due to less steric hindrance and a greater partial positive charge on the carbonyl carbon, as the presence of two alkyl groups in ketones reduces reactivity.
