Which of the following species do not show disproportionation reaction ?

Options

A. `ClO^(-)`
B. `ClO_(4)^(-)`
C. `ClO_(2)^(-)`
D. `ClO_(3)^(-)`

Answer

B

Explanation

`ClO_(4)^(-)` does not disproportionate because in this oxoanion chlorine is present in its highest oxidation state `(+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)^(-))`
