Concept of configuration and chirality, axes of symmetry, plane of symmetry, center of symmetry. Representation of molecules using projection formulae - Fischer, Wedge, Sawhorse and Newmann. Geometric Isomerism: Methods of determination of configuration of geometric isomers. Optical isomerism: Enantiomers and diastereomers. Nomenclature of stereoisomers including E and Z, D and L and R and S designations. Conformations of ethane, butane, cyclohexane with their energy profile diagrams. Conformational analysis of mono- and di-substituted cyclohexanes. Types of strains: Angle strain (Baeyer Strain), transannular strain (Prelog Strain), torsional strain (Pitzer strain).
