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, 3d 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 ofCr = x + 2 (-1) = + 1
`rArr x = + 3`
`Cr^(3+)` occupies 3 orbitals and its coordination number in the given complex is 6.
