The similarities and the differences between VB theory and MO theory are to be stated. Concept introduction: When two atomic orbitals come close to each other they lose their identity and form new pair of orbitals knows as molecular orbitals. Among the two molecular orbitals formed, one has energy lower than the atomic orbitals is known as bonding molecular orbital and the other has energy higher than the atomic orbitals and is known as antibonding molecular orbital. The electrons in molecular orbitals are filled according to Aufbau’s principle and Hund’s rule. Valence bond theory gives an explanation corresponding to the chemical bonding in a molecule. According to this theory, bonding between atoms takes place due to the overlapping of half-filled atomic orbitals.

Question

Definition Definition Theory that explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. VBT gives a quantum mechanical approach to the formation of covalent bonds with the help of wave functions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
