Q. The correct order of $C - O$ bond length among $CO, C O_{3}^{2 -}, C O_{2}$ is

$CO < C O_{3}^{2 -} < C O_{2}$

$C O_{3}^{2 -} < C O_{2} < CO$

$CO < C O_{2} < C O_{3}^{2 -}$

$C O_{2} < C O_{3}^{2 -} < CO$

More single bond character in resonance hybrid, more is the bond length. Hence the increasing bond length is $CO < C O_{2} < C O_{3}^{2 -}$

Q. The correct order of C−O bond length among CO,CO32−​,CO2​ is

CO<CO32−​<CO2​

CO32−​<CO2​<CO

CO<CO2​<CO32−​

CO2​<CO32−​<CO
