Question

In the compounds of the type `POX_3`, P atoms show multiple bonding of the type
A. ` p pi -d pi `
B. `d pi -d pi `
C. ` p pi -d pi `
D. none of these

Answer 1

Correct Answer - C
The structure of `POX_(3)` is as follows :

It involves a `pi` bond between P and O in which half filled d-orbitals of P overlaps the half filled p-orbitals of O. thus it involves `d pi -p pi` multiple bonding.
