Vedclass · Answer

(D) The crystal field splitting energy $(\Delta)$ depends on the oxidation state of the central metal ion and the nature of the ligand. $1$. Higher oxidation state of the central metal ion leads to greater splitting energy. $2$. Strong field ligands (like $NH_3$) cause greater splitting compared to weak field ligands (like $F^-$,$Cl^-$,$H_2O$). $3$. In $[Co(NH_3)_6]^{3+}$,the oxidation state of $Co$ is $+3$ and $NH_3$ is a strong field ligand. $4$. In the other complexes,the oxidation state of $Co$ is $+2$ and the ligands are weaker. Therefore,$[Co(NH_3)_6]^{3+}$ has the highest crystal field stabilisation energy.
