Systematic Nomenclature of organic compounds aids chemical communication through the presentation of methods and their use in forming reasonable, acceptable, and unambiguous names for organic compounds. It describes in a common language so that the nomenclature is made useful and understandable for both undergraduate and graduate students. A diagrammatic presentation is given to create interest in the topic along with a comparison of different nomenclature operations for some compounds with some typical structures. A number of examples are discussed in a systematic step-by-step approach. This book provides in-depth information of nomenclature of organic compounds. It contains 14 chapters covering all aspects of nomenclature which include Main Principles, Classification, IUPAC Nomenclature of Hydrocarbons, Nomenclature of compounds with two different functional groups, Aromatic Hydrocarbons, Fused Polycylic Aromatic and Unsaturated Hydrocarbon, Carbocyclic Compounds, Heterocyclic Compounds, Bridged Systems, Spiro Hydrocarbons, Terpenoids, Steroids, Macrocyclic Compounds, and Stereochemical notations. The book is meant for the students at undergraduate and postgraduate level and will be equally useful for instructors, researchers, and industrial scientists in the areas of organic chemistry, general chemistry, biochemistry, pharmaceutical chemistry, and industrial chemistry.
