In acidec medium, H(2)O(2) changes Cr(2)...

In acidec medium, `H_(2)O_(2)` changes `Cr_(2)O_(7)^(2-)` to `CrO_(5)` which has two `(-O-O-)` bonds. Oxidation state of Cr in `CrO_(5)` is

A

`+5`

B

`+3`

C

`+6`

D

`-10`

Text Solution

Verified by Experts

The correct Answer is:
C
The structure of `CrO_(5)` is

Out of five oxygen atoms, four are involved in peroxide linkages. Therefore, oxidation state of Cr is `+6` .
