Bond orders: CO 32-: 1.33 CO 2: 2 CO: 3 The higher the bond order, the lesser the bond length. So, the order of bond length of C - O is: CO < CO 2< CO 32-

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

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

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

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

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

Bond orders:
$C O_{3}^{2 -} : 1.33$
$C O_{2} : 2$
$CO : 3$
The higher the bond order, the lesser the bond length.
So, the order of bond length of $C - O$ is:
$CO < C O_{2} < C O_{3}^{2 -}$

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

CO2​<CO32−​<CO

CO<CO32−​<CO2​

CO32−​<CO2​<CO

CO<CO2​<CO32−​
