Question: In $ PO_4^{3-} $ ion, the formal charge on each oxygen atom and $ P-O $ bond order respectively are
[DPMT 2004]
Options:
A) $ -0.75,\ 1.25 $
B) $ -0.75,\ 1.0 $
C) $ -0.75,\ 0.6 $
D) $ -3,\ 1.25 $
Show Answer
Answer:
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 $
