An introduction to the principles of molecular structure and chemical bonding. Topics include: the electronic structure of atoms, bonding models and Molecular Orbital Theory, symmetry and point groups, structure and bonding of ionic solids, structure and bonding of transition metal complexes, stereochemistry and conformational isomerism. Prerequisite: AUCHE 112. Note: Students who completed AUCHE 110 between 2021 and 2023 may also use that course as a prerequisite to AUCHE 230.
