A metal complex having the composition C...

A metal complex having the composition `Cr(NH_3)_4Cl_2 Br` has been isolated in two forms A and B. The form A reacts with `AgNO_3` to give a white precipitate readily soluble in dilute aqueous ammonia whereas B gives a pale yellow precipitate soluble in concentrated ammonia.
The hybridization of Cr in the complexes A and B, respectively, is

A

`d^2sp^3 and sp^3d^2`

B

`sp^3 d^2 and d^2 sp^3`

C

`sp^3 d and dsp^3`

D

`d^2 sp^3 and d^2 sp^3`

Text Solution

Verified by Experts

The correct Answer is:
D
As in boht the complexs Cr is in + 3 oxidation state so it undergoes `d^2sp^3` hybridization and the geometry is octahedral.
