Draw the d-orbital splitting for an octahedral and a tetrahedral complex.

See explanation

Explanation:

In an octahedral crystal field, the metal is at the centre of an octahedron with ligands at the six corners of the octahedron. Approach of the ligand splits the orbitals into higher energy eg and lower energy t2g orbitals. The eg orbitals are 0.6∆o above the bari centre while the t2g orbitals are -0.4∆o below the bari centre.

In a tetrahedral crystal field, the tetrahedral crystal field splitting ∆t= 4/9∆o. In the tetrahedral crystal field, the t2 orbitals are at a higher energy and are +0.4∆t above the bari centre while the e orbitals are at a lower energy and are -0.6∆t below the bari center.
