Which of the following is the strongest nucleophile?

Question

Quizplus · Accepted Answer

The strength of a nucleophile can be determined by its ability to donate electrons and form a bond with a positively charged species. A stronger nucleophile has a higher electron density on the nucleophilic atom. In this case, the nucleophiles are all negatively charged and have the same central atom (oxygen), but differ in their substituents. The nucleophile in choice D has a highly electronegative substituent (fluorine) which withdraws electron density from the oxygen, making it a stronger nucleophile compared to the others.
