Which of the following is an example of a disproportionation reaction?

Options

  1. A6KOH + 3MnO 2 + 6KClO 3 → 3K 2 MnO 4 + 6KCl + 3H 2 O
  2. BK 2 Cr 2 O 7 + 4H 2 SO 4 → K 2 SO 4 + Cr 2 (SO 4 ) 3 + 4H 2 O + 3(O)
  3. CK 2 Cr 2 O 7 + 4KCl + 6H 2 SO 4 → 2CrO 2 Cl 2 + 6KHSO 4 + 3H 2 O
  4. D3MnO 4 2– + 4H + → 2MnO 4 – + MnO 2 + 2H 2 O

Correct answer

D. 3MnO 4 2– + 4H + → 2MnO 4 – + MnO 2 + 2H 2 O

Step-by-step solution

Correct Option is : (D) 3MnO 4 2– + 4H + → 2MnO 4 – + MnO 2 + 2H 2 O
