Out of `HO^(-)` or `HS^(-)` which one is (a) better nucleophile and (B) a better base ? |
|
Answer» (a) S is less electronegative than O, therefore, it can donate a pair of electrons more easily than O. Thus, `HS^(-)` is a better nucleophile than `HO^(-)`. (b) Since O-H bond is stronger than S-H bond, therefore `HO^(-)` has a greater tendency to accept a proton than `HS^(-)` and hence `HO^(-)` is a better base than `HS^(-)`. |
