WebThe Lewis Concept of Covalent Bonding failed to explain the geometry and magnetic properties of molecules. In 1927, Heitler and London put forward Valence Bond Theory (VBT). In 1930, Hund, Huckle and Mullikan put forward Molecular Orbital Theory (MOT). WebAlthough the Lewis structure and molecular orbital models of oxygen yield the same bond order, there is an important difference between these models. The electrons in the Lewis structure are all paired, but there are two unpaired electrons in the molecular orbital description of the molecule.
