Vedclass · Answer

(D) The magnitude of crystal field splitting $(\Delta_o)$ depends on the nature of the ligand (spectrochemical series) and the oxidation state of the metal ion.$1$. In option $A$,$H_2O$ is a stronger field ligand than $F^-$,so $[Fe(H_2O)_6]^{3+} > [FeF_6]^{3-}$ is correct.$2$. In option $B$,$en$ (ethylenediamine) is a stronger field ligand than $NCS^-$,so $[Fe(en)_3]^{3+} > [Fe(NCS)_6]^{3-}$ is correct.$3$. In option $C$,$CN^-$ is a strong field ligand compared to $H_2O$,so $[Fe(CN)_6]^{4-} > [Fe(H_2O)_6]^{2+}$ is correct.$4$. In option $D$,$NH_3$ is a stronger field ligand than $H_2O$. Therefore,the order should be $[Fe(NH_3)_6]^{2+} > [Fe(H_2O)_6]^{2+}$. The given order $[Fe(H_2O)_6]^{2+} > [Fe(NH_3)_6]^{2+}$ is incorrect.

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

In which of the following,complex ions are not in correct order with respect to their magnitude of crystal field splitting?
