Vedclass · Answer

(D) The electronic configurations of the metal ions in the given octahedral complexes are as follows:$A. [Cr(H_2O)_6]^{3+}$: $Cr^{3+}$ is $3d^3$. In an octahedral field,this corresponds to $t_{2g}^3 e_g^0$. Thus,$A-II$.$B. [Fe(H_2O)_6]^{3+}$: $Fe^{3+}$ is $3d^5$. With a weak field ligand like $H_2O$,it is high spin: $t_{2g}^3 e_g^2$. Thus,$B-III$.$C. [Ni(H_2O)_6]^{2+}$: $Ni^{2+}$ is $3d^8$. In an octahedral field,this corresponds to $t_{2g}^6 e_g^2$. Thus,$C-IV$.$D. [V(H_2O)_6]^{3+}$: $V^{3+}$ is $3d^2$. In an octahedral field,this corresponds to $t_{2g}^2 e_g^0$. Thus,$D-I$.Therefore,the correct matching is $A-II, B-III, C-IV, D-I$.

$I$	$II$
$(a). [Cr(H_2O)_6]^{2+}$	$[Cr(H_2O)_6]^{3+}$
$(b). [Fe(H_2O)_6]^{3+}$	$[Fe(CN)_6]^{3-}$
$(c). [Fe(CN)_6]^{3-}$	$[Ru(CN)_6]^{3-}$
$(d). [NiF_6]^{4-}$	$[NiF_6]^{2-}$
