Question

ligand field will cause splitting of energy levels of 3d orbitals of the central metal ion..........

splitting of energy ieveis of 3d obitals of the central metal ion. 6. Ligand field will cause Draw the energy levels of the 3d ortbitals of metal complexes in (a) octahedral, (b) tetrahedral, (c) square planar, (d) linear configurations. (e) Briefly explain the key factor which determines the relative energy level of the five 3d orbitals in different configurations. (20 % )
