In organic chemistry, knowing how to perform chemical transformations step by step or how to assign the correct configuration and nomenclature to organic compounds is something that requires more than just a strong theoretical basis. There are some considerations that professors and lecturers often do not have time to explain during regular courses. Moreover, while there are many excellent textbooks available on the theory of organic chemistry, the same cannot be said for rational guides to organic chemistry problems. This guide provides study problems that are suitable for different levels of organic chemistry, and successfully used by students attending organic chemistry classes in chemistry, pharmacy, pharmaceutical chemistry, agriculture, biology, natural sciences, environmental sciences, chemical engineering, biotechnology, and industrial chemistry. The problems are all solved and fully explained. Every single step of each problem is shown in a logical and easy-to-follow format, with constant reference to theory. In addition to solved problems, the book provides methods, strategies, and explanations that help students master organic chemistry problems. The book includes the following chapters: Nomenclature of hydrocarbons; Stereochemistry; Reactions of alkenes and alkynes; Nucleophilic substitution and elimination reactions; Reactions of aldehydes and ketones; Reactivity of carboxylic acids and their derivatives; Enolate ions: reactions of ?,?-unsaturated carbonyl compounds; Amines; Chemistry of aromatic compound; Substitutive nomenclature; Preparation schemes. The book is provided with extensions online.
