The coordination number and oxidation number of `Cr` in `K_(3)[Cr(C_(2)O_(4))_(3)]` are, respectively,

A

`4 and +2`

B

`6 and +3`

C

`3` and `-3`

D

`3` and `0`

Text Solution

Verified by Experts

The correct Answer is:
B
Coodination number
= Number of ligands `xx` denticity
`3xx2` ( bidendate)
`=6`
`overset(+3)K[overset(+3)(Cr)overset(-2xx3)((C_(2)O_(4))_(3))]^(3-) :. "Oxidation state of " Cr= +3`.
