The bond order in \[CO_{3}^{2-}\]ion between \[C-O\] is [Pb. PMT 2004]
A) Zero
B) 0.88
C) 1.33
D) 2
Correct Answer:
C
Solution :
We know that carbonate ion has following resonating structures Bond order \[=\frac{\text{Total number of bonds between atoms}}{\text{Total number of resonating structure}}\] \[=\frac{1+1+2}{3}=\frac{4}{3}=1.33\].
