Which one of the following reactions indicates the reducing ability of hydrogen peroxide in basic medium?

Options

A $HOCl + {H}_{2}{O}_{2} \to {H}_{3}{O}^{+} + {Cl}^{-} + {O}_{2}$
B $PbS + 4{H}_{2}{O}_{2} \to {PbSO}_{4} + 4{H}_{2}O$
C $2{MnO}_{4}^{-} + 3{H}_{2}{O}_{2} \to 2{MnO}_{2} + 3{O}_{2} + 2{H}_{2}O + 2{OH}^{-}$
D ${Mn}^{2 +} + {H}_{2}{O}_{2} \to {Mn}^{4 +} + 2{OH}^{-}$

Correct answer

C. $2{MnO}_{4}^{-} + 3{H}_{2}{O}_{2} \to 2{MnO}_{2} + 3{O}_{2} + 2{H}_{2}O + 2{OH}^{-}$

Step-by-step solution

In option $\left(A\right)$ and $\left(C\right)$ reducing action of hydrogen peroxide is shown.

For reducing ability ${H}_{2}{O}_{2}$ changes to ${O}_{2}$ , i.e. oxidize, so in option ' $A$ ' & $C ' ' {O}_{2}$ is formed but ' $A$ ' is in acidic medium so option - $C$ is correct.

$2{MnO}_{4}^{-} + 3{H}_{2}{O}_{2} \to 2{MnO}_{2} + 3{O}_{2} + 2{H}_{2}O + 2{OH}^{-}$
