Q95 / 270 · NDA 2016 (Phase 2) · General Ability

Which one of the following species is not capable of showing disproportionation reaction?

  • A
    $\mathrm{ClO}^{-}$
  • B
    $\mathrm{ClO}_2^{-}$
  • C
    $\mathrm{ClO}_3^1$
  • Correct answer
    D
    $\mathrm{ClO}_4^1$

Solution

$\mathrm{In} \mathrm{ClO}_4^{-}, \mathrm{Cl}$ is in its maximum oxidation state that is +7 so it cannot go disproportionation reaction because it cannot further oxidised.

Hence, the correct answer is option: 'D'.
