NEET Chemistry Nucleophilic Addition MCQ Question
Which of the following statements about nucleophilic addition reactions of aldehydes and ketones is correct?
Nucleophiles attack the carbonyl carbon from a direction perpendicular to the plane of sp² hybridized orbitals.
The carbonyl group in aldehydes is less electrophilic than in ketones, making aldehydes less reactive.
The intermediate formed during nucleophilic addition retains sp² hybridization throughout the reaction.
Cyanohydrins are formed from the addition of hydrogen chloride to carbonyl compounds.
Correct Answer
Detailed Explanation
A nucleophile indeed attacks the electrophilic carbon atom of the carbonyl group from a direction approximately perpendicular to the plane of sp² hybridized orbitals, leading to the formation of a tetrahedral intermediate. This is a key feature of nucleophilic addition reactions in aldehydes and ketones.
