Question

In the general mechanism of nucleophilic addition to a carbonyl group, what is the role of the nucleophile and what intermediate is formed?

Accepted Answer

The nucleophile donates electrons to the electrophilic carbon, forming a tetrahedral intermediate.

Answer

The nucleophile donates electrons to the carbonyl oxygen, forming a hexagonal intermediate.

Answer

The nucleophile accepts electrons from the carbonyl oxygen, forming a linear intermediate.

Answer

The nucleophile accepts electrons from the electrophilic carbon, forming a planar intermediate.
