`[Cr(H_2 O)_6]Cl_3` (at no. of Cr = 24) has a magnetic moment of `3.83 B.M`. The correct distribution of `3d` electrons the chromium of the complex.

Options

A. `3d_(xy)^(1) , 3d_(yz)^(1) , 3 d_(zx)^(1)`
B. `3d_(xy)^(1) , 3d_(yz)^(1) , 3d_(z^(2))^(1)`
C. `3d_((x^(2) - y^(2)))^(1) , 3d_(z^(2))^(1) , 3d_(xz)^(1)`
D. `3d_(xy)^(1) , 3d_((x^(2)- y^(2)))^(1) , 3d_(yz)^(1)`

Answer

A

Explanation

Magnetic moment indicates that there are three unpaired electrons present in chromium . These must be present in lower energy orbitals which are `3d_(xy) , 3d_(yz) ` and `3d_(xz)`
