NEET Chemistry Nucleophilic Addition Assertion Reason Question
Assertion (A): Aldehydes and ketones undergo nucleophilic addition reactions rather than electrophilic addition reactions. | Reason (R): The nucleophile attacks the electrophilic carbon atom of the polar carbonyl group from a direction approximately perpendicular to the plane of sp2 hybridised orbitals.
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 and reason are both true as aldehydes and ketones undergo nucleophilic addition due to the electrophilic nature of the carbonyl carbon, which is attacked perpendicularly by the nucleophile, changing carbon's hybridisation from sp2 to sp3.
