The oxidation states of Cr in `[Cr(H_(2)O)_(6)]CI_(3)[Cr(C_(6)H_(6))_(2)] and K_(2)[Cr(CN_(2))(O)_(2)(O_(2))(NH_(3))]` respectively are -

A

`+3,+4and +6`

B

`+3,+2and+4`

C

`+3,0and +6`

D

`+3,0and +4`

Text Solution

Verified by Experts

The correct Answer is:
C
`[overset(+5)(Cr)(H_(2)O)_(6)]CI_(3),[overset(0)Cr(C_(6)H_(6))_(2)]`
in `K_(2)[Cr(CN_(2))(O)_(2)(O_(2))(NH_(3))]`compound number let ,the oxidation number of Cr be x

or,2+x-2-4-2+0=0
or,x=+6
