MCQ
The bond order in $CO_3^{2 - }$ ion between $C - O$ is
- A$0$
- B$0.88$
- ✓$1.33$
- D$2$
✓
Answer
Correct option: C.
$1.33$
(c) We know that carbonate ion has following resonating structures
Bond order $ = \frac{{{\rm{Total \,number\,of \,bonds \,between \,atoms}}}}{{{\rm{Total\, number\, of \,resonating \,structure}}}}$
$ = \frac{{1 + 1 + 2}}{3} = \frac{4}{3} = 1.33$.
