Q. Example on Crystal field splitting in octahedral complexes?
Here four ligands lie in one plane and the other two in a plane perpendicular to the first plane. Six ligands are at the comers of a regular octahedron and they all lie along the three perpendicular axes, s, y and:. Thus we see that all those orbitals which lie in the direction of these axes will experience a stronger force of repulsion as compared to the orbitals which lie between the axes.
The dx2 - y2 and dZ2 orbitals which fie along the axes will be repelled more by the ligands and will be higher in energy than dxy, dyz and dX set of orbitals.
The transition metal complexes are known to be paramagnetic in character. CFT helps us to understand the magnetic properties in terms of magnetic susceptibility measurements. The m
