Short Summary of IUPAC Nomenclature of Organic Compounds IntroductionThe purpose of the IUPAC system of nomenclature is to establish an international standard ofnaming compounds to facilitate communication. The goal of the system is to give each structurea unique and unambiguous name, and to correlate each name with a unique and unambiguousstructure.
I. Fundamental Principle IUPAC nomenclature is based on naming a molecule's longest chain of carbons connected bysingle bonds, whether in a continuous chain or in a ring. All deviations, either multiple bonds oratoms other than carbon and hydrogen, are indicated by prefixes or suffixes according to aspecific set of priorities.
II. Alkanes and CycloalkanesAlkanes are the family of saturated hydrocarbons, that is, molecules containing carbon andhydrogen connected by single bonds only. These molecules can be in continuous chains (calledlinear or acyclic), or in rings (called cyclic or alicyclic). The names of alkanes and cycloalkanesare the root names of organic compounds. Beginning with the five-carbon alkane, the number ofcarbons in the chain is indicated by the Greek or Latin prefix. Rings are designated by the prefix"cyclo". (In the geometrical symbols for rings, each apex represents a carbon with the number ofhydrogens required to fill its valence.)
