The value of n in : `MnO_(4)^(-)+8H^(+)+n erarr Mn^(2+)+4H_(2)O` is

A

`M/2`

B

`M/3`

C

`M/4`

D

`M/5`

Text Solution

Verified by Experts

The correct Answer is:
D
The tendency to form +2 ionic state increase on moving down the group due to the inert pair effect. Most characteristic oxidation state for lead and tin are +2 and +4 respectively.
