Which of the following has highest nucleophilicity ?A. `F^(-)`B. `OH^(-)`C. `CH_(3)^(-)`D. `NH_(2)^(-)` |
|
Answer» Correct Answer - C Nucleophilicity is directly related to the basic strength if nucleophilic atoms belong to the same period of the periodic table. Order of basic strength of conjugates acids: `HF gt H_(2)O gt NH_(3) gt CH_(4)` Order of basic sterngth of conjugate bases: `CH_(3)^(-) gt NH_(2)^(-)gt OH^(-) gtF^(-)` Thus, order of nucleophilicity is as follows: `CH_(3)^(-) gt NH_(2)^(-) gt OH^(-) gt F^(-)` |
