In the compounds of the type `POX_3`, P atoms show multiple bonding of the type

Options

A. `p pi , dpi`
B. `d pi, dpi `
C. `p pi - dpi `
D. no multiple bond is present

Answer

C

Explanation

In `POX_(3)`, the hybridisation state of P is `sp^(3)` phosphorous has vacant d-orbitals which will overlap with the P orbitals of oxygen thereby resulting in formation of `p pi -dpi ` bond.
