NEET Chemistry Nucleophilic Addition MCQ Question
Consider a diagram showing the nucleophilic addition mechanism involving an aldehyde and a nucleophile. After the nucleophile attacks the carbonyl carbon, what is the immediate hybridization change observed at the carbon atom?

sp2 to sp3
sp3 to sp2
sp to sp2
sp3 to sp
Correct Answer
Detailed Explanation
According to the NCERT context, during nucleophilic addition, the nucleophile attacks the carbonyl carbon, changing its hybridization from sp2 to sp3 as a tetrahedral alkoxide intermediate is formed.
