Find out the compounds that will disproportionate in their aqueous solution. I ClO 4 - ⁡ → + 0.36 V ClO 3 - ⁡ → + 0.33 V C l O 2 → + 0.66 V O C l - → + 0.40 V 1 2 C l 2 → + 1.36 V C l - I I MnO 4 - ⁡ → + 0.56 V MnO 4 2 - ⁡ → + 2.22 V M n O 2 → + 0.95 V M n 3 + → + 1.55 V M n 2 + → - 0.19 V M n

Options

  1. A(I) (II) C l O 2 , C l 2 M n O 4 2 - , M n 3 +
  2. B(I) (II) C l O 3 - , O C l - M n O 2 , M n 2 +
  3. C(I) (II) O C l - only M n O 2 , M n 2 +
  4. D(I) (II) C l O 3 - only M n O 2 only

Correct answer

A. (I) (II) C l O 2 , C l 2 M n O 4 2 - , M n 3 +

Step-by-step solution

If the reaction sequence is written in reduction order then if right side reduction potential is higher than left side reduction potential then that compound will disproportionate.
