Question

[ Cr ( H 2 O )6] Cl 3 (atomic number of Cr =24 ) has a magnetic moment of 3.83 BM. The correct distribution of 3 d-elections in the chromium present in the complex is (A) 3d1xy,3d1yz,3d1zx (B) 3d1xy,3d1yz,3d1z2 (C) 3d1(x2y2)3d1z23d1zx (D) 3d1xy,3d1(x2y2),3d1xz

Magnetic moment indicates that there are three unpaired electrons present in chromium. These must be present in lower energy orbitals which are 3d1 xy, 3d1 yz and 3d1 xz.

Q. $[C r (H_{2} O)_{6}] C l_{3}$ (atomic number of $C r = 24$ ) has a magnetic moment of $3.83 BM$ . The correct distribution of $3 d$ -elections in the chromium present in the complex is

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

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

$3 d_{_{(x^{2} y^{2})}}^{1} 3 d_{_{z^{2}}}^{1} 3 d_{z x}^{1}$

$3 d_{x y}^{1}, 3 d_{_{(x^{2} y^{2})}}^{1}, 3 d_{x z}^{1}$

Magnetic moment indicates that there are three unpaired electrons present in chromium. These must be present in lower energy orbitals which are $3 d_{x y}^{1}, 3 d_{yz}^{1}$ and $3 d_{x z}^{1} .$
