When `KMnO_(4)` acts as an oxidising agnet and ultimetely from `MnO_(4)^(2-), MnO_(2), Mn_(2)O_(3)`, and `Mn^(2+)`, then the number of electrons transferred in each case, respectively, are

Options

A. 4,3, 1,5
B. 1,5,3, 7
C. 1,3,4,5
D. 3,5, 7, I

Answer

C

Explanation

(c) In `KMnO_4`, the O.N. of Mn is +7, in `MnO_(4)^(-2)` +6, in `MnO_2` +4 in `Mn_2O_3`, +3 and in `Mn^(2+)`, it is +2. The difference being 1,3,4 and 5 respectively.
