In PO ₄³⁻, the formal charge on each oxygen atom and the 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
Correct answer
C. -0.75,1.25
Step-by-step solution
Bond order = Number of bonds Number of Resonating structures = 5 4 =1.25 Three unit negative charge is being shared by four O atoms. Formal charge =-3 / 4
