Options:
Answer:
D
Solution:
The enolate O- carries three lone pairs, while the carbonyl O and the OCH3 oxygen each carry two. The nucleophilic atoms are the O-, the central (α) carbon that carries the π electron density, and the carbonyl O. The OCH3 oxygen's lone pair is involved in conjugation with the C=O bond. Therefore, there are 3 nucleophilic atoms.
