Which of thefollowing species do not show disporoportionationreaction

1.	Which of thefollowing species do not show disporoportionationreaction and why ? CIO^(-),CIO_(2)^(-),CIO_(3)^(-) and CIO_(4)^(-) Also write reaction for each of the species that disproportinates
Answer» Solution :The oxidation STATE of CI in all the given species are `overset(+1)CIO, overset(+3)CIO, overset(+5)CIO_(3), overset(+7)CIO_(4)` out of above species `CIO_(4)` does not undergo disproportionation since in this oxanion chloringis ALREADY present in the higherst oxidation state +7 and hence cannot be further oxidation all the remaing oxanotion have oxdation states LOWER undergo disproportion reaction as shown below `3overset(+1)CIOrarr2overset(-1)CI+overset(+5)CIO_(3),overset(+3)CIO_(2)rarr2CIO_(3),4CIO_(3)^(-)rarr3 CIO_(4)^(-)`
