What do you understand by crystal field splitting? Draw figure to show splitting of degenerate d-orbitals in an octahedral crystal field.
The crystal field splitting, depends upon the field produced by the ligand and charge on the metal ion. Some ligands are able to produce strong fields in which case, the splitting will be large whereas others produce weak fields and consequently result in small splitting of d orbitals. Therefore the d orbital will be degenrate in two set such as t2g and eg orbital .
