Vedclass · Answer

(D) Disproportionation is a specific type of redox reaction in which a species is simultaneously reduced and oxidized to form two different products.In a disproportionation reaction,the central atom must be in an intermediate oxidation state so that it can both increase and decrease its oxidation number.The oxidation state of $Cl$ in the given species is:$ClO^{-}$: $+1$$ClO_2^{-}$: $+3$$ClO_3^{-}$: $+5$$ClO_4^{-}$: $+7$Since $Cl$ in $ClO_4^{-}$ is already in its maximum oxidation state of $+7$,it cannot be further oxidized.Therefore,$ClO_4^{-}$ cannot undergo a disproportionation reaction.Hence,the correct option is $(D)$.

Which species among the following does not show disproportionation reactions?
