Which among the following has the maximum nucleophilicity?
Answer»
`F^(-)` `OH^(-)` `CH_(3)^(-)` `NH_(2)^(-)`.
Solution :as the electronegativity of the atom holding the negative charge decreases its electron RELEASING tendency or nucleophilicity INCREASES. `CH_(3)^(-)` is the strongest NUCLEOPHILE because CARBON is the least ELECTRONEGATIVE.
