Coordination number of Cr is 6. A complete entity with `C_(2)O_(4)^(-2)`, en superoxide as ligands is `[Cr(C_(2)O_(4))_(x)(en)_(y)(O_(2))_(z)]^(+)`. The ratio of x: y : z is

A

`1:1:2`

B

`1:1:1`

C

`1:2:3`

D

`2:1:1`

Text Solution

Verified by Experts

The correct Answer is:
A
(en) and (ox) are bidentate ligands `(O_(2)^(-))` is monodentate by verification `1xx2+1xx2+2xx2=6`
