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.
