Molecular Orbital Theory

Molecular Orbital Theory. Electrons in atoms exist in atomic orbitals Electrons in molecules exist in molecular orbitals (MOs) Using Schrödinger equation, we can calculate the shapes and energies of MOs. Molecular Orbital Theory. Rules: combination of n atomic orbitals gives n MO

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

Molecular Orbital Theory

Molecular Orbital Theory. The goal of molecular orbital theory is to describe molecules in a similar way to how we describe atoms, that is, in terms of orbitals, orbital diagrams, and electron configurations Describes the properties based on the bonding within the molecule.
