Solution

The correct option is D $C O < C O_{2} < C O_{3}^{2 -}$
Bond length $\propto \frac{1}{% π character}$
As can be seen from the structures of $C O, C O_{3}^{2 -} a n d C O_{2}$ , $π$ character is maximum in $C O$ and least in $C O_{3}^{2 -}$ . Hence, Bond length follows the order $C O < C O_{2} < C O_{3}^{2 -}$ .

The correct order of increasing C−O bond length of CO,CO2−3 and CO2 is:

The correct option is D CO<CO2<CO2−3Bond length ∝1% π character As can be seen from the structures of CO,CO2−3 and CO2, π character is maximum in CO and least in CO2−3. Hence, Bond length follows the order CO<CO2<CO2−3.
