Vedclass · Answer

(B) The magnitude of crystal field splitting energy,$\Delta_0$,depends on the oxidation state of the central metal ion and the nature of the ligand.$1$. Higher oxidation state of the metal ion leads to larger $\Delta_0$. Here,$Co$ is in $+3$ state in options $B, C,$ and $D$,while it is in $+2$ state in option $A$.$2$. Among ligands,the spectrochemical series follows the order: $C_2O_4^{2-} $3$. Since $CN^-$ is a strong field ligand,it causes the maximum splitting.Therefore,the magnitude of $\Delta_0$ is maximum for $[Co(CN)_6]^{3-}$.

$I$. $NCS^{-}$	$II$. $S^{2-}$
$III$. $en$	$IV$. $SCN^{-}$

In which of the following octahedral complex species the magnitude of $\Delta_0$ will be maximum?
