Among the following, identify the species with an atom in `+6` oxidation state.

A

`MnO_(4)^(-)`

B

`Cr(CN)_(6)^(3-)`

C

`NiF_(6)^(2-)`

D

`CrO_(2)Cl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D

In `MnO_(4)^(-)`, oxidation state of `Mn` is `+7`
In `Cr(CN)_(6)^(3-)`, oxidation state of `Cr` is `+3`
In `NiF_(6)^(2-), Ni` is in `+4` oxidation state.
In `CrO_(2)Cl_(2)`, oxidation state of `Cr` is `+6`.
