In which of the following reactions of hydrogen peroxide acts as an oxidizing agent (either in acidic, alkaline, or neutral medium)?
(i) \(2F{e}^{+2}+{H}_{2}{O}_{2}\to\)
(ii) \(2{\mathrm{MnO}}_{4}^{-}+6{\mathrm{H}}^{+}+5{\mathrm{H}}_{2}{\mathrm{O}}_{2}\to\)
(iii) \({I}_{2}+{H}_{2}{O}_{2}+2O{H}^{-}\to\)
(iv) \(M{n}^{+2}+{H}_{2}{O}_{2}\to\)

a

(ii), (iii)

b

(i), (iv)

c

(i), (iii)

d

(ii), (iv)

✓ Correct answer: b)

(i), (iv)

Explanation

In reactions (i) and (iv), H₂O₂ acts as an oxidizing agent:

  • (i) Fe²⁺ → Fe³⁺
  • (iv) Mn2+→ Mn7+
    Thus, correct answer: (B) (i), (iv).
