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

Options

A. `CO_2`
B. `CH_3COO^(-)`
C. `CO`
D. `CO_3^(2-)`

Answer

D

Explanation

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.
