The species which does not undergo disproportionation reaction is :

The species which does not undergo disproportionation reaction is :

Options

  1. AClO3−\mathrm{ClO}_3^{-}
  2. BClO−\mathrm{ClO}^{-}
  3. CClO2−\mathrm{ClO}_2^{-}
  4. DClO4−\mathrm{ClO}_4^{-}

Correct answer

D. ClO4−\mathrm{ClO}_4^{-}

Step-by-step solution

ClO4−→x+{(−2)×4}=−1⇒x=+7\mathrm{ClO}_4^{-} \rightarrow x+\{(-2) \times 4\}=-1 \Rightarrow x=+7 Chlorine is in its maximum oxidation state, so disproportionation not possible in ClO4−\mathrm{ClO}_4^{-}.
