Step-by-step solution
d-orbital is degenerate which split into two levels e g and t 2 g in the presence of ligands. This splitting is due to the presence of ligands. This is called the crystal-field splitting and the energy difference between the two levels is called the crystal-field splitting energy, Δ 0 .
