Postulates of MOT:
1. Molecular orbital theory asserts that atomic orbitals no longer hold significant meaning after atoms form molecules. Molecular orbital theory holds electrons reside in molecular orbitals that are distributed over the entire molecule.
2. Atomic orbitals of comparable energy and proper symmetry combine together to form molecular orbitals. The total number of orbitals is conserved; the number of molecular orbitals equals the number of original atomic orbitals.
3. When atomic orbitals interact, if added them it results in a bonding orbital and if subtracted then an antibonding orbital is obtained. Antibonding orbitals are denoted with an asterisk (*).
4. The movement of electrons in a molecular orbital is influenced by all the nuclei of combining atoms.
