Vedclass · Answer

(A) The magnitude of crystal field splitting energy $\left(\Delta_0\right)$ depends on the oxidation state of the metal ion and the nature of the metal ion itself.For a given ligand and oxidation state,$\Delta_0$ generally increases with the effective nuclear charge and the size of the $d$-orbitals.Among the given $3d$ series metal ions in the $+3$ oxidation state,$Cr^{3+}$ has a $d^3$ configuration.In octahedral complexes,$Cr^{3+}$ exhibits a high crystal field splitting energy due to the stability of the $t_{2g}^3$ configuration.Comparing the given complexes,$[Cr(OH_2)_6]^{3+}$ has the highest $\Delta_0$ value among the choices provided.

The complex with the highest magnitude of crystal field splitting energy $\left(\Delta_0\right)$ is
