Flash based tools to help with the construction of MO diagrams:
- "energy levels" shows how the form of the bonding and antibonding orbitals, the bond order and atomic charges vary in a diatomic molecule with the electronegativity of the two atoms involved
- "Molecular orbital diagram maker" shows how a complex MO diagram can be made by a drag and drop approach using symmetry adapted components
Using these tools, a student should be able to:
- explain how the bonding between two atoms varies with their electronegativity in terms of the bond order between them and their charges
- construct MO diagrams for typical inorganic molecules and complexes
The 'energy levels' tool is useful in lectures as it shows the relationship between the molecular orbital diagram and the bond character of a polar covalent bond and combines a graphical and a numerical approach.
The 'MO diagram maker' is useful as for students for practice and as a self-test of their understanding.
Through in-class discussion and through performance in tutorials.
