# The species given below that does NOT show

Question:

The species given below that does NOT show disproportionation reaction is :

1. $\mathrm{BrO}_{4}^{-}$

2. $\mathrm{BrO}^{-}$

3. $\mathrm{BrO}_{2}^{-}$

4. $\mathrm{BrO}_{3}^{-}$

Correct Option: 1

Solution:

In $\mathrm{BrO}_{4}^{\ominus}, \mathrm{Br}$ is in highest oxidation state $(+7)$, So it cannot oxidise further hence it cannot show disproportionation reaction.
