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. `3,5,7,1`

Answer

C

Explanation

`{:(e^(-)+MnO_(4)^(ө),rarrMnO_(4)^(2-),,,),(3e^(-)+MnO_(4)^(ө),rarrMnO_(2),,,),(4e^(-)+2MnO_(4)^(ө),rarrMn_(2)O_(3),,,),(5e^(-)+MnO_(4)^(ө),rarrMn^(2+),,,):}`
