Which of the following has the highest nucleophilicity ?

Options

A. `F^(-)`
B. `OH^(-)`
C. `CH_(3)^(-)`
D. `NH_(2)^(-)`

Explanation

As the electronegativity of the atom decreases `(FgtOgtNgtC)`, its tendency to donate a pair of electrons, i.e. nucleophilicity increases. Thus `CH_(3)`, has highest nucleophilicity.
