- A2
The dxy orbital has four lobes lying between the x and y axes in the xy plane. The dz² orbital has two lobes along z with a torus around the centre.
All five d orbitals have the same general four-lobed/axial angular family in an isolated atom, but their orientations differ. In a ligand field, their energies can split.
Sketch axes first, then place dxy lobes between axes and dz² lobes on the z axis with the doughnut in the xy plane.
Do not put dxy lobes on the axes or draw dz² as a simple p orbital.
