Which among the following is a set of nucleophiles ?

Options

A. `H^(+),NH_(3),Cl^(-)`
B. `BF_(3),H_(2)O,NH_(3)`
C. `AlCl_(3),BF_(3),NH_(3)`
D. `CN^(-),H_(2)O,R -OH`

Answer

D

Explanation

All molecules or ions with free pair of electrons or at least one `pi`-bond can act as nucleophile.
Among given species `CN^(-) H_(2) underset(ddot)(ddot(O))` and `R - underset(ddot)(ddot(O))H` are nucleophiles
