Which of the following species do not show disproportionation reaction and why?
`BrO^(ө)` (hypobromirte ion), `BrO_(2)^(ө)` (bromite ion), `BrO_(3)^(ө)`(bromate ion),and `BrO_(4)^(ө)` (perbromate ion)

Text Solution

Verified by Experts

`BrO^(ө)` does not disproptionate beacse in this oxoanion, `Br` is present in its highest oxidation state, i.e, `+7`. The disproprtionation for other three oxanions of `Br` is as follows:
`Boverset(+1)BrO^(ө)rarr2overset(-1)Br^(ө)+overset(+5)BrO_(3)^(ө)`
`6overset(+3)BrO_(2)^(ө)overset(hv)rarr4overset(+5)BrO_(3)^(ө)+2overset(-1)Br^(ө)`
`4overset(+5)BrO_(3)^(ө)rarr3 overset(+7)BrO_(4)^(ө)+overset(-1)Br^(ө)`.
