In PO43−,\mathrm{PO}_{4}^{3-}, the formal charge on each oxygen atom and the P−O\mathrm{P}-\mathrm{O} bond order respectively are

Options

  1. A-0.75,0.6
  2. B-0.75,1.0
  3. C-0.75,1.25
  4. D-3,1.25

Correct answer

C. -0.75,1.25

Step-by-step solution

Bond order = Number of bonds  Number of Resonating structures =54=1.25=\frac{\text{ Number of bonds }}{\text{ Number of Resonating structures }}=\frac{5}{4}=1.25 Three unit negative charge is being shared by four O\mathrm{O} atoms. Formal charge =−3/4=-3 / 4
