The species given below that does NOT show disproportionation...

The species given below that does NOTNOT show disproportionation reaction is:

Options

  1. ABrO4−{BrO}_{4}^{-}
  2. BBrO−{BrO}^{-}
  3. CBrO2−{BrO}_{2}^{-}
  4. DBrO3−{BrO}_{3}^{-}

Correct answer

A. BrO4−{BrO}_{4}^{-}

Step-by-step solution

In BrO4⊖,Br{BrO}_{4}^{⊖}, Br is in highest oxidation state (+7)( + 7 ), So it cannot oxidise further hence, it cannot show disproportionation reaction.
