Why do sequence of increasing energy of molecular orbital is different for some compounds?
Asked by | 03 Jan, 2013, 03:50: PM
Expert Answer
The greater the overlap, the more the bonding orbital is lowered and the anti-bonding orbital is raised in energy relative to atomic orbitals. For e.g., the extent of overlapping in case of sigma orbital is more than that in pi orbital. Consequently, the energy of a ?2pz is lower than the energy of bonding ?2px or ?2py MOs.
So, basically it depends upon the extent of overlaping of orbitals.
