Vedclass · Answer

(A) The bond length is inversely proportional to the bond order.Bond order $(BO)$ for these species is as follows:$1$. For $CO$: The bond order is $3.0$.$2$. For $CO_2$: The resonance hybrid structure shows an average bond order of $2.0$.$3$. For $CO_3^{2-}$: The resonance hybrid structure shows an average bond order of $1.33$.Since the bond order follows the order $CO > CO_2 > CO_3^{2-}$,the bond length follows the inverse order: $CO < CO_2 < CO_3^{2-}$.

The $C-O$ bond length in $CO$,$CO_2$ and $CO_3^{2-}$ follows the order.
