Which of the following is the best nucleophile in an S_N2 reaction?

Question

Quizplus · Accepted Answer

Ethoxide ion is the best nucleophile among the options because it is less hindered compared to tert-butoxide and tert-pentoxide ions, allowing it to attack the substrate more easily than the bulkier options. Isopropoxide ion is also less hindered but ethoxide ion is generally considered a stronger nucleophile due to its smaller size and ability to donate electrons more effectively.
