The oxidation states not shown by Mn in given reaction is : 3MnO42−+4H+⟶2MnO4−+MnO2+2H2O3 \mathrm{MnO}_4^{2-}+4 \mathrm{H}^{+} \longrightarrow 2 \mathrm{MnO}_4^{-}+\mathrm{MnO}_2+2 \mathrm{H}_2 \mathrm{O} A. +6 B. +2 C. +4 D. +7 E. +3 Choose the most appropriate answer from the options given below :The oxidation states not shown by Mn in given reaction is : 3 MnO_4^ 2- +4 H^ + 2 MnO_4^ - +MnO_2+2 H_2 O A. +6 B. +2

Options

  1. AD and E only
  2. BB and D only
  3. CA and B only
  4. DB and E only

Correct answer

D. B and E only

Step-by-step solution

In the following reaction 3MnO42−+4H+⟶2MnO4−+MnO2+2H2O3 \mathrm{MnO}_4^{2-}+4 \mathrm{H}^{+} \longrightarrow 2 \mathrm{MnO}_4^{-}+\mathrm{MnO}_2+2 \mathrm{H}_2 \mathrm{O} The oxidation states not shown by Mn in given reaction is : 3 MnO_4^ 2- +4 H^ + 2 MnO_4^ - +MnO_2+2 H_2 O A. +6 B. +2
So +2 and +3 oxidation state is not shown by Mn .
