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

Explanation

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 :
`{:(+1" "" " -1" "" " +5),(3ClO^(-)" " to" " 2Cl" "+ClO_(3)^(-)),(+3" " " "+5" "" " -1),(6ClO_(2)^(-)" " overset(hu)to" " 4ClO_(3)" "+2Cl^(-)),(+5" " " "-1" " " " +2),(4ClO_(3)" " to" " Cl^(-)" "+3ClO_(4)^(-)):}`
