Which of the following species, do not show disproportionation reaction and why? CIO^(-),CIO_(2)^(-),CIO_(3)^(-)andCIO_(4)^(-) Also write reaction for each of the species that disproportionates.

Which of the following species, do not show disproportionation reactio

1.	Which of the following species, do not show disproportionation reaction and why? CIO^(-),CIO_(2)^(-),CIO_(3)^(-)andCIO_(4)^(-) Also write reaction for each of the species that disproportionates.
Answer» Solution :Among the OXOANIONS of CHLORINE listed above `ClO_(4)^(-)` does not disproportionate because in this oxoanion chlorine is present in its highest oxidation state that is, +7. The disproportionation reactions for the other three oxoanions of chlorine are as FOLLOWS : `overset(+1)(3ClO^(-))tooverset(-1)(2Cl^(-))+overset(+5)(ClO_(3)^(-))` `overset(+3)(6ClO_(2)^(-))overset(hv)tooverset(+5)(4ClO_(3)^(-))+overset(-1)(2Cl^(-))` `overset(+5)(4ClO_(3)^(-))tooverset(-1)(Cl^(-))+overset(+7)(3ClO_(4)^(-))`
