[Cr(H₂O)₆]Cl₃ (At. no. of Cr = 24) has a magnetic momen of 3.83 B.M. The correct distribution of 3d electrons in the chromium of the complex is

$$3d_{x\,y}^1,\,3d_{y\,z}^1,\,3d_{z^2}^{1}$$

$$3d_{\left( {x^2 - y^2} \right)}^1,\,3d_{z^2}^1,\,3d_{xz}^1$$

$$3d_{x\,y}^1,\,\,3d_{\left( {x^2 - y^2} \right)}^1,\,3d_{y\,z}^1$$

$$3d_{x\,y}^1,\,3d_{y\,z}^1,\,3d_{x\,z}^1$$
