Question

who is most nucleophilic OH- or H2O​

Answer 1

Answer:

Notice that when oxygen is part of the hydroxide ion, it bears a negative charge, and when it is part of a water molecule, it is neutral. The O of -OH is a better nucleophile than the O of H 2O, and results in a faster reaction rate.
