Manganese show oxidation state from `+ 2` to `+ 7`. The most oxidizing state known in aqueous solution is

A

`+2`

B

`+3`

C

`+4`

D

`+7`

Text Solution

Verified by Experts

The correct Answer is:
D
Elements in higher oxidation state are oxidizing agents. Because in higher oxidation state they have smaller size.
Decreasing order of size the cation is
`Mn^(2+) gt Mn^(3+)to Mn^(7+)`
Smaller the size of the cation more the tendncy to ghain electron and act as strong oxidizing agent.
