The correct order of Cl-O bond lengths in ClO-,ClO2-,ClO3- and ClO4- is as follows ClO4- < ClO3- < ClO2- < ClO- Bond length propto (1/B o n d text order) or Bond length propto (1/ textExtent of delocalization)

Q. The correct order of $Cl - O$ bond lengths in $Cl O^{-}, Cl O_{2}^{-}, Cl O_{3}^{-}$ and $Cl O_{4}^{-}$ is

$Cl O^{-} < Cl O_{2}^{-} < Cl O_{3}^{-} < Cl O_{4}^{-}$

$Cl O_{4}^{-} < Cl O_{3}^{-} < Cl O_{2}^{-} < Cl O^{-}$

$Cl O_{3}^{-} < Cl O_{4}^{-} > Cl O_{2}^{-} > Cl O^{-}$

$Cl O_{4}^{-} = Cl O_{3}^{-} = Cl O_{2}^{-} = Cl O^{-}$

The correct order of $Cl - O$ bond lengths in $Cl O^{-}, Cl O_{2}^{-}, Cl O_{3}^{-}$ and $Cl O_{4}^{-}$ is as follows
$Cl O_{4}^{-} < Cl O_{3}^{-} < Cl O_{2}^{-} < Cl O^{-}$
Bond length $\propto \frac{1}{B o n d order}$
or Bond length $\propto \frac{1}{Extent of delocalization}$

Q. The correct order of Cl−O bond lengths in ClO−,ClO2−​,ClO3−​ and ClO4−​ is

ClO−<ClO2−​<ClO3−​<ClO4−​

ClO4−​<ClO3−​<ClO2−​<ClO−

ClO3−​<ClO4−​>ClO2−​>ClO−

ClO4−​=ClO3−​=ClO2−​=ClO−
