The course commences with chemical reactions, concepts involved in chemical equations and an introduction to nomenclature of inorganic and organic substances. The gas laws are presented and then the electronic structure of gaseous atoms is developed. This leads to the concept of an orbital and provides a basis for the later description of ionic and covalent bonding and molecular geometry. Intermolecular forces are introduced which then leads to the chemistry of solutions and their properties. Finally, the chemistry of carbon, organic chemistry, is studied. Sub-topics include classes of organic compounds and common functional groups; and conclude with an introduction to biological chemistry.
