CHAPTER 4: MOLECULAR ORBITAL THEORY

CHAPTER 4: MOLECULAR ORBITAL THEORY. It is clear that hybridized valence bond theory does not explain much of the observed phenomena for small molecules such as paramagnetism or UV absorption and a better theory needs to be introduced to rationalize these experimental observations.

Molecular Orbital Theory (MO – T)

Molecular Orbital Theory (MO – T). Atoms form bonds by sharing of electrons. Atoms can share 2, 4 or 6 electrons to form single, double or triple covalent bonds. It is actually impossible to determine the exact position of an electron, however, it is
