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

Options

A. `NO _(3) ^(-)`
B. `PO_(4) ^(3-)`
C. `CO_(3) ^(2-)`
D. `NO_(2) ^(-)`

Answer

B

Explanation

In `PO_(4)^(30),P` is `sp^(3)-`hybridized It forms four P-O. `sigma-`bond by overlap of `sp^(3)-`orbitals of P with P-orbital of O. The `pi-`bond is, however. Formed overlep of p-orbital of O and d-orbital of P.

N and C, on the other hand , cannot form `pi-dpi` bond since they do not have d-orbitals.
