Question

In the general mechanism of nucleophilic addition to a polar carbonyl group, which specific elementary step serves as the Rate Determining Step (RDS)?

Answer: B

💡 Solution & Explanation

In NAR, the approach and attack of the nucleophile onto the electrophilic carbonyl carbon (changing its hybridization from $sp^2$ to $sp^3$) is sterically and electronically hindered, making it the slow, Rate Determining Step (RDS) of the reaction.
