Question

[Cr(H2O)6]Cl3 (at no. of Cr = 24) has a magnetic moment of 3.83 B.M. The correct distribution of 3d electrons in the chromium of the complex (A) 3dxy1,3dyz1,3xz1 (B) 3dxy1,3dyz1,3dz21 (C) (3d1x2-y2),3d1 z2, 3d1xz (D) 3d1xy,(3d1 x2-y2,) 3d1yz

Cr3+ = ls22s22p6, 3s23p63d3. The 3d1xy 3d1xz 3d1yzz has lower energy

Q. $[C r (H_{2} O)_{6}] C l_{3}$ (at no. of $C r = 24$ ) has a magnetic moment of $3.83 B . M .$ The correct distribution of 3d electrons in the chromium of the complex

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

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

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

$3 d_{x y}^{1}, (3 d_{x}^{1} 2 - y^{2},) 3 d_{yz}^{1}$

$C r^{3 +} = l s^{2} 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6} 3 d^{3}$ . The $3 d_{x y}^{1} 3 d_{x z}^{1} 3 d_{yz}^{1} z$ has lower energy
