Hybridization also changes the energy levels of the orbitals. * The formation of PCl5 molecule requires 5 unpaired electrons. The valence bond theory was proposed by Heitler and London to explain the formation of covalent bond quantitatively using quantum mechanics. Since there are no unpaired electrons, it undergoes excitation by promoting one Almost always, some sort of intermixing i.e., hybridization of pure atomic orbitals is observed before the bond formation to confer maximum stability to the molecule. The hybridization theory is often seen as a long and confusing concept and it is a handy skill to be able to quickly determine if the atom is sp 3, sp 2 or sp without having to go through all the details of how the hybridization had happened..
