    Application of the principles of organic chemistry to an understanding of why organic compounds react as they do; to develop the ability to predict the course of a chemical reaction to allow for the design of controlled and selective chemical transformations.

    CHEM302 Organic Chemistry focuses on how the concepts and techniques of organic chemistry may be applied to interpret chemical reactions and to plan chemical transformations. The principles involved apply equally to reactions performed in the laboratory and to those proceeding in living systems.

    Paper Structure

    The topics covered in CHEM302 are:

    • Frontier molecular orbital theory and reactive intermediates.
      • Examination of the transformations involving carbocations, carbenes and free radicals, including reactions that involve structural rearrangements.
      • Pericyclic reactions such as electrocyclic reactions; cycloadditions and 1,3-dipolar additions will also be studied.
      • An underlying theoretical basis will be the use of pictorial representations of molecular orbitals to interpret the selectivity of chemical reactions.
    • Heterocyclic chemistry.
      • Structure, nomenclature, aromaticity and reactivity of heterocycles.
      • Synthesis of heterocycles via condensation and pericyclic reactions.
      • Cross-coupling reactions of heterocycles.
    • Molecules of living systems.
      • Neighbouring group effects: bridged reaction intermediates, rate acceleration, rearrangements, organometallic catalysis and asymmetric induction.

    There are three lectures and one 4-hour laboratory class each week.
