Vedclass · Answer

(A) $[Co(NH_3)_6]^{3+}$: $NH_3$ is a strong field ligand. $Co^{3+}$ is $3d^6$. In octahedral field,it becomes $t_{2g}^6 e_g^0$ $(II)$.$[CoF_6]^{3-}$: $F^-$ is a weak field ligand. $Co^{3+}$ is $3d^6$. In octahedral field,it becomes $t_{2g}^4 e_g^2$ $(III)$.$[Ni(CO)_4]$: $CO$ is a strong field ligand. $Ni$ is in $0$ oxidation state $(3d^8 4s^2)$. It forms a tetrahedral complex with configuration $e^4 t_2^4$ (often represented as $t^4 e^6$ in some contexts for tetrahedral splitting) $(IV)$.$[Fe(CN)_6]^{3-}$: $CN^-$ is a strong field ligand. $Fe^{3+}$ is $3d^5$. In octahedral field,it becomes $t_{2g}^5 e_g^0$ $(I)$.Therefore,the correct match is $A-II, B-III, C-IV, D-I$.

List-$I$ (Complex)	List-$II$ (Electronic configuration of metal/ion)
$A. [Co(NH_3)_6]^{3+}$	$I. t_{2g}^5 e_g^0$
$B. [CoF_6]^{3-}$	$II. t_{2g}^6 e_g^0$
$C. [Ni(CO)_4]$	$III. t_{2g}^4 e_g^2$
$D. [Fe(CN)_6]^{3-}$	$IV. t^4 e^6$
