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

Structure of Atom

Solution:

$Cr^{3+} = ls^{2}2s^{2}2p^{6}, 3s^{2}3p^{6}3d^{3}$. The $3d^{1}_{xy} 3d^{1}_{xz} 3d^{1}_{yz}z$ has lower energy
