Molecular Orbital Theory allows us to predict the distribution of electrons within a molecule. This allows us to predict properties such as bond order, magnetism and shape.
Concept #1: Understanding Molecular Orbital Theory
In MO theory, electrons are seen as being delocalized or spread out over a molecule instead of concentrated in a covalent bond.
Example #1: Use a MO diagram to write the electron configuration of each of the following:
Example #2: Use a MO diagram to write the electron configuration of each of the following:
Concept #2: Calculating Bond Order
By calculating the bond order it is possible to determine the stability of the bonds within a molecule.
Practice: Use a MO diagram to determine if the following compound exists or not.
O2 2- and B2 -
