The course presents a broad survey of the phenomena isomerism, optical isomerism due to independent asymmetric carbon atoms, and stereoisomerism of compounds containing identical asymmetric carbons atoms. Topics to be discussed will include asymmetry of inorganic elements, alkenes, alkylidene, cycloalkanes, spirans and biphenyl; dissymmetry of restricted rotation and molecular overcrowding; enantiomers; symmetry element; racemic modification; epimerization; and resolution. Other relevant topics such as absolute and configuration; Rectus and Sinister system; stereochemistry of simple derivatives of cyclopropane, cyclobutane, cyclopentane, and decalins; and acyclic and cyclic system will also be discussed.
