Question

In PO43– ion, the formal charge on each O atom and P–O bond order are respectively

(a) –0.75, 0.6

(b) – 0.75, 1.0

(c) –0.75, 1.25

(d) –3, 1.25

Answer 1

Correct option (c) –0.75, 1.25

Explanation:

PO43– is a hybrid of following structures

P-O bond order = 5/4 = 1.25;

Charge on each O = -3/4 = -0.75
