Which of the following has highest nucleophilicity ?

Options

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

Answer

C

Explanation

Lesser the electronegativity of the donor atom, more is its tendency to donate a pair of electron and stronger is the nucleophile. Electronegativity of C, N, 0, F are in the order `Fgt0gtNgtC`. Therefore `CH_(3)` is the strongest nucleophilic, i.e., it has highest nucleophilicity.
