The oxidation number , d-orbital occupation and co-ordination number of cr in the complex
Cis-`[Cr(en)_(2)Cl_(2)]Cl` are respectively .

A

`+3,ed` and 4

B

`+3,4d` and 6

C

`+3,3d` and 6

D

`+2`, 3d and 6

Text Solution

Verified by Experts

The correct Answer is:
C
Oxidation state of `Cr= x+2(-1) = +1implies x= +3`.
`Cr^(3+)` occupies 3d orbitals and its coordination number in the given complex is 6.
