The number of electrons involved in the conversion of `MnO_(4)^(-)` to `MnO_(2)` is

A

1

B

2

C

5

D

3

Text Solution

Verified by Experts

The correct Answer is:
D
In alkaline medium, `KMnO_(4)` acts as an oxidising agent as follows -
`MNO_(4)^(-)+2H_()O+3e^(-)rarrMnO_(2)+4OH^(-)`
Thus three electrons per molecule of are involved.
