The textbook conforms to the requirements for training enhancement through the use of innovative technologies, competence-based learning in particular. The factors systematizing the content are issues of electronic structure of the carbon atom and organogens, chemical bonds, mutual influence of atoms within a molecule, conjugation and aromaticity, mechanisms of the most important types of reactions, and stereochemical repres entations. Much attention is paid to application of physicochemical methods of analysis. The authors have extended the section on the role of stereochemical structure in the manifestation of pharmacological activities of organic compounds. The authors present a set of ne
