MCQ
The species given below that does NOT show disproportionation reaction is :
  • A
    $\mathrm{BrO}_{2}^{-}$
  • ✓
    $\mathrm{BrO}_{4}^{-}$
  • C
    $\mathrm{BrO}^{-}$
  • D
    $\mathrm{BrO}_{3}^{-}$
✓

Answer

Correct option: B.
$\mathrm{BrO}_{4}^{-}$
b
In $\mathrm{BrO}_{4}^{\ominus}, \mathrm{Br}$ is in highest oxidation state $(+7),$ Soit cannot oxidise further it only reduced hence it cannot show disproportionation reaction
