    In \[PO_{4}^{3-}\]ion, the formal charge on each oxygen atom and \[P-O\]bond order respectively are  [DPMT 2004]

    A)                 \[-0.75,\ 1.25\] 

    B)                 \[-0.75,\ 1.0\]

    C)                 \[-0.75,\ 0.6\]   

    D)                 \[-3,\ 1.25\]

    Correct Answer: A

    Solution :

               Bond order\[=\frac{\text{Total number of bonds between atoms}}{\text{Total number of resonating structure}}\]                                                \[=\frac{5}{4}=1.25\]
