Lanthanides Electronic Configuration

[CrH2O6]Cl3 a...

Question

$[C r (H_{2} O)_{6}] C l_{3}$ (atomic number of $C r = 24$ ) had a magnetic moment of $3.83 B . M .$ The correct distribution of $3d$electrons in the chromium present in the complex is :

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

Solution

The correct option is A $3 d_{x y}^{1}, 3 d_{y z}^{1}, 3 d_{z x}^{1}$
$[C r (H_{2} O)_{6}] C l_{3}$
+3 n = 3
magnetic moment
$μ = \sqrt{n (n + 2)}$ B.M.
and in octahedral complex these three electron have $3 d_{x y}^{1}, 3 d_{y z}^{1}, 3 d_{z x}^{1}$ configuration
