Which of the following is the strongest nucleophile towards $CH X_{3} I$ in ethanol?

A $CH X_{3} COOH$
B $CH X_{3} CH X_{2} O X^{-}$
C $H X_{2} O$
D $CH X_{3} CH X_{2} OH$

Answer: B

For the same attacking atom, the negatively charged species is a much better nucleophile than its neutral conjugate acid. Ethoxide is the strongest base and the strongest nucleophile of these four.
