A nucleophilic reagent is

A

`CO_2`

B

`BF_3`

C

`dAlCl_3`

D

`NH_3`

Text Solution

Verified by Experts

The correct Answer is:
D
A nucleophilic reagent acts by donating or sharing its electrons . Among the given molecules only : `NH_3` can act thus. `AlCl_3` and `BF_3` are electron-deficient molecules and O=C=`O^3` is a saturated molecule .
