Vedclass · Answer

(B) $1$. Analyze the electronic configuration and crystal field splitting for each complex:$2$. $[Cr(CN)_6]^{4-}$: $Cr^{2+}$ is $d^4$. $CN^-$ is a strong field ligand,causing pairing. Configuration: $t_{2g}^4 e_g^0$. Unpaired electrons in $e_g = 0$.$3$. $[Ni(en)_3]Cl_2$: $Ni^{2+}$ is $d^8$. Configuration: $t_{2g}^6 e_g^2$. Unpaired electrons in $e_g = 2$.$4$. $[Sc(H_2O)_6]^{3+}$: $Sc^{3+}$ is $d^0$. Configuration: $t_{2g}^0 e_g^0$. Unpaired electrons in $e_g = 0$.$5$. $[V(H_2O)_6]^{2+}$: $V^{2+}$ is $d^3$. Configuration: $t_{2g}^3 e_g^0$. Unpaired electrons in $e_g = 0$.$6$. Re-evaluating the options: The question asks for the maximum number of unpaired electrons in the $e_g$ set. Based on the configurations,$[Ni(en)_3]^{2+}$ has $2$ unpaired electrons in the $e_g$ orbitals.

Which of the following complexes has the maximum number of unpaired electrons in the $e_g$ set of orbitals?
