Question

Calculate the formal charge on each o atom and po bond order in po4

Answer 1

Hello dear,

● Answer -

Effective charge on each oxygen = -0.75

Bond order P-O bond = 1.25.

● Explanation -

- (PO4)3- has -3 charge delocalized on 4 O atoms.

- Therefore, effective charge on each atom -

x = -3/4 = -0.75

Bond order is calculated by -

BO = [2×n(O) + charge] / n(O)

BO = [2×4 - 3)] / 4

BO = (8-3) / 4

BO = 1.25

Therefore, effective charge on each oxygen is -0.75 and bond order is 1.25.

Hope this helped...
