Determine whether the below-given species is a strong, intermediate, or weak nucleophile. Would this nucleophile add directly to a carbonyl or wait for the carbocation formation before adding to the carbonyl?

• A. It is a strong nucleophile that will directly attack the carbonyl.
• B. It is a strong nucleophile that will attack the carbonyl after carbocation formation.
• C. It is a weak nucleophile that will attack the carbonyl after carbocation formation.
• D. It is a weak nucleophile that will directly attack the carbonyl.
