Chemistry-Nucleophilic Addition
NEET Chemistry Nucleophilic Addition MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Consider a diagram showing a nucleophile attacking the electrophilic carbon atom of the polar carbonyl group in an aldehyde. Which of the following best describes the change in hybridization of the carbon atom during this nucleophilic addition reaction?
A
The hybridization changes from sp2 to sp3.
B
The hybridization changes from sp3 to sp2.
C
The hybridization remains sp2 throughout the reaction.
D
The hybridization changes from sp to sp3.
Correct Answer
Option A
Detailed Explanation
During the nucleophilic addition reaction, a nucleophile attacks the electrophilic carbon atom of the carbonyl group, changing the carbon's hybridization from sp2 to sp3 as a tetrahedral alkoxide intermediate is formed.
