$\mathrm{KMnO}_4$ on reaction with $\mathrm{KOH}$ does not give

  • Correct answer
    A
    $\mathrm{MnO}_2$
  • B
    $\mathrm{K}_2 \mathrm{MnO}_4$
  • C
    $\mathrm{H}_2 \mathrm{O}$
  • D
    nascent oxygen.

Solution

$\begin{array}{r}2 \mathrm{KMnO}_4+2 \mathrm{KOH} \longrightarrow 2 \mathrm{~K}_2 \mathrm{MnO}_4+ \\ \mathrm{H}_2 \mathrm{O}+[\mathrm{O}]\end{array}$

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