IUPAC Nomenclature and Functional Groups

The video tutorial covers the nomenclature of carboxylic acids, explaining the functional group, suffixes, and prefixes used in naming. It provides examples of common and IUPAC names for various carboxylic acids, discusses homologous series, and addresses complex structures and substituents. The tutorial also covers advanced nomenclature involving multiple functional groups, emphasizing the importance of priority in naming.
