In `PO_(4)^(3-)` the formal charge on each O-atom and `P-O` bond order respectively are .

Options

A. `-0.75 , 0.6`
B. `-0.75, 1.0`
C. `-0./75, 1. 25`
D. `-3, 1. 25`

Answer

C

Explanation

The structure f `P _(4) ^(3-) ,is `

Here three units negative charge is shared by four O atoms and five bond pairs are shared between four P-O bonds
`therefore` Formal charge `= - 3//4=- 0.75`
Bond order of `P-O and = 5//4 = 1. 25.`
