Identify the species in which the metal atom is in +6 oxidation state.

A

`MnO_4^(-)`

B

`[Cr(CN)_6]^(3-)`

C

`[NiF_6]^(2-)`

D

`CrO_2Cl_2`

Text Solution

Verified by Experts

The correct Answer is:
D
In `CrO_2Cl_2," O.S of "Cr=+6`
`MnO_4^(-)," O.S. of "Mn=+7`
`Cr(CN)_6^(3-)," O.S of "Cr=+3`
`NiF_6^(3-)," O.S. of " Ni=+4`
