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

A

`-0.75, 1.25`

B

`-3,1.25`

C

`-0.75,1.0`

D

`-0.75,0.6`

Text Solution

Verified by Experts

The correct Answer is:
A
(All other options are wrong)
Formal charge on each oxygen atom
`=("Total charge")/("Number of O-atoms")=(-3)/4=0.75`
`.^(-)O-overset(O)overset(||)underset(O^(-))underset(|)(P)-O^(-)`
Structureof `PO_(4)^(3-)` ion
Bond order of each P-O bond =`5/4=1.25`
