Among the following ions the p `pi`- d `pi` overlap could be present in

A

`NO_2^-`

B

`NO_3^-`

C

`PO_4^(3-)`

D

`CO_3^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
C
In P-O bond, `pi`-bond is formed by the sidewise overlapping of d-orbital of P and p-orbital of oxygen. Hence, it is formed by `ppi` and `dpi` -overlapping.

In nitrogen and carbon, no vacant d-orbital is present. So , they do not form `ppi-dpi` bond.
