R-7.0 Introduction This section is concerned only with the main principles for specification of stereochemistry in organic compounds [for a more detailed description, see Section E of the IUPAC
Nomenclature of Organic Chemistry; see also Pure Appl. Chem., 45, 11-30 (1976)]. The spatial structure of an organic compound
is systematically indicated by one or more affixes added to a name that does not itself prescribe stereochemical configuration; such affixes are generally called stereodescriptors and do not change
the name or the numbering of a compound established by the principles of nomenclature described in other sections of these recommendations. Thus, stereoisomers, such as enantiomers and
cis/trans isomers, have names that differ only in the stereodescriptors used. By contrast, certain trivial names imply their own stereochemical configuration, for example, fumaric acid and
