Q. What is the correct order of increasing $C - O$ bond length of $CO, C O_{3}^{2 -}$ and $C O_{2} ?$

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

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

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

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

Q. What is the correct order of increasing C−O bond length of CO,CO32−​ and CO2​?

CO32−​<CO2​<CO

CO2​<CO32−​<CO

CO<CO32−​<CO2​

CO<CO2​<CO32−​

Q. What is the correct order of increasing $C - O$ bond length of $CO, C O_{3}^{2 -}$ and $C O_{2} ?$

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

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

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

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