partial double bond where π electron is distributed along two C - O bond.

partial double bond where two π electrons are distributed along three C - O bond. Since, single bond, double bond and triple bonds have longest, intermediate and shortest bond lengths respectively, therefore order of bond lengths between C and O is CO 3- > HCO 2- > CO 2 > CO

Q. The correct arrangement of the species in the decreasing order of the bond length between carbon and oxygen in them is

$C O_{2}, H C O_{2}^{-}, CO, C O_{3}^{2 -}$

$CO, C O_{3}^{- 2}, C O_{2}, H C O_{2}^{-}$

$CO, C O_{2}, H C O_{2}^{-}, C O_{3}^{- 2}$

$C O_{3}^{- 2}, H C O_{2}^{-}, C O_{2}, CO$

Q. The correct arrangement of the species in the decreasing order of the bond length between carbon and oxygen in them is

CO2​,HCO2−​,CO,CO32−​

CO,CO3−2​,CO2​,HCO2−​

CO,CO2​,HCO2−​,CO3−2​

CO3−2​,HCO2−​,CO2​,CO

$C O_{2}, H C O_{2}^{-}, CO, C O_{3}^{2 -}$

$CO, C O_{3}^{- 2}, C O_{2}, H C O_{2}^{-}$

$CO, C O_{2}, H C O_{2}^{-}, C O_{3}^{- 2}$

$C O_{3}^{- 2}, H C O_{2}^{-}, C O_{2}, CO$
