The correct order of oxidizing power of the given ions is

Options

  1. AVO ₂⁺ Cr ₂ O ₇²⁻ MnO ₄⁻
  2. BVO ₂⁺ MnO ₄⁻ Cr ₂ O ₇²⁻
  3. CMnO ₄⁻ Cr ₂ O ₇²⁻ VO ₂⁺
  4. DCr ₂ O ₇²⁻ VO ₂⁺ MnO ₄⁻

Correct answer

A. VO ₂⁺ Cr ₂ O ₇²⁻ MnO ₄⁻

Step-by-step solution

In VO ₂⁺, V is in +3 oxidation state. Cr ₂ O ₇²⁻ Cr is in +6 oxidation state. MnO ₄⁻ Mn is in +7 oxidation state. Oxidising power means substance have more tendency to accept electron. Mn is in highest oxidation state so it have more oxidising power. MnO ₄⁻ Cr ₂ O ₇²⁻ VO ₂⁺
