Question

The correct order of increasing oxidizing power in the series …………….. 

(a) VO₂⁺< Cr₂O²⁻ ₇ < MnO^–₄  

(b) Cr₂O₇²⁻ <  VO₂⁺ < MnO^–₄

(c) Cr₂O₇²⁻  <  MnO^–₄ <  VO₂⁺

(d) MnO^–₄  < Cr₂O₇²⁻  <  VO₂⁺

Answer 1

(a) VO₂⁺< Cr₂O²⁻ ₇ < MnO^–₄  

greater the oxidation state, higher is the oxidising power.
