Vedclass · Answer

(D) Magnetic moment $(\mu) = \sqrt{n(n+2)} 	ext{ } B.M.$Given $\mu = 3.83 	ext{ } B.M.$$3.83 = \sqrt{n(n+2)} \implies n \approx 3$This indicates there are $3$ unpaired electrons.For the complex $[Cr(H_2O)_6]Cl_3$,the oxidation state of $Cr$ is $+3$.The electronic configuration of $Cr$ $(Z=24)$ is $[Ar] 3d^5 4s^1$.Thus,$Cr^{3+}$ is $[Ar] 3d^3$.According to Hund's rule,the $3$ electrons in the $3d$ orbitals occupy the $t_{2g}$ set $(d_{xy}, d_{yz}, d_{xz})$ singly.Therefore,the distribution is $3d_{xy}^1, 3d_{yz}^1, 3d_{xz}^1$.

$[Cr(H_2O)_6]Cl_3$ $(At. \text{ } no. \text{ } of \text{ } Cr = 24)$ has a magnetic moment of $3.83 \text{ } B.M.$ The correct distribution of $3d$ electrons in the chromium of the complex is
