NEET Chemistry Nucleophilic Addition MCQ Question
Which of the following statements about nucleophilic addition reactions of aldehydes and ketones is correct?
Cyanohydrins are formed from the reaction of aldehydes and ketones with hydrogen cyanide in the presence of a base.
The addition of sodium hydrogensulphite to carbonyl compounds results in the formation of stable products with no equilibrium.
The nucleophilic attack in these reactions typically occurs from a direction parallel to the plane of sp2 hybridized orbitals.
Ammonia derivatives add to the carbonyl group without the need for acid catalysis.
Correct Answer
Detailed Explanation
Cyanohydrins are indeed produced from the reaction of aldehydes and ketones with hydrogen cyanide, which is facilitated by a base as mentioned in the NCERT context. The other statements contain inaccuracies regarding stability, direction of attack, and the need for acid catalysis.
