Vedclass · Answer

(C) In $[Co(NH_3)_6]Cl_3$,the oxidation state of $Co$ is $+3$.The electronic configuration of $Co^{3+}$ is $[Ar] 3d^6$.Since $NH_3$ is a strong field ligand,it causes pairing of electrons in the $d$-orbitals.Thus,the $6$ electrons occupy the $t_{2g}$ orbitals,and the $e_g$ orbitals remain empty.The $CFSE$ is calculated as: $CFSE = (n_{t_{2g}} 	imes -0.4 \Delta_0) + (n_{e_g} 	imes 0.6 \Delta_0)$.$CFSE = (6 	imes -0.4 \Delta_0) + (0 	imes 0.6 \Delta_0) = -2.4 \Delta_0$.

The crystal field stabilization energy of $[Co(NH_3)_6]Cl_3$ is $......... \Delta_0$
