Among the species CO(2),CH(3)COO',CO,CO(...

Among the species `CO_(2),CH_(3)COO',CO,CO_(3)^(2-)HCHO` which has the veakest carbon-oxygen bond

A

`CO_2`

B

`CH_3COO^(-)`

C

`CO`

D

`CO_3^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
D
Among the given species. The bond dissociation energy of `C - O` bond is minimum in case of `CO_3^(2-)` by which C - O bond become more weaker in `CO_3^(2-)` or the bond order of `CO_3^(2-)`(1.33) is minimum so the bond becomes weaker.
