NEET Chemistry Nucleophilic Addition MCQ Question
Which of the following statements about nucleophilic addition reactions of aldehydes and ketones is correct?
The nucleophile attacks the carbonyl carbon from a direction perpendicular to the sp2 hybridized orbitals.
Nucleophilic addition reactions are always irreversible and do not form intermediates.
The hybridization of the carbonyl carbon remains sp2 throughout the nucleophilic addition.
Addition of ammonia and its derivatives to carbonyls results in stable products without dehydration.
Correct Answer
Detailed Explanation
The nucleophile indeed attacks the electrophilic carbon of the carbonyl group from a direction approximately perpendicular to the plane of sp2 hybridized orbitals, leading to a change in hybridization to sp3, forming a tetrahedral alkoxide intermediate.
