Since the carbons are singly-bonded, the suffix begins with "an".
- There are two carbons in the main chain this gives the root name "eth".
- However, the name 2-hydroxyethanamine unambiguously refers to the same compound.
Would render the name as 2-aminoethanol, which is preferred. In many cases, lack of rigor in applying all such nomenclature rules still yields a name that is intelligible - the aim, of course, being to avoid any ambiguity in terms of what substance is being discussed.įor instance, strict application of CIP priority to the naming of the compound The name of the parent hydrocarbon is modified by the application of the highest-priority functional group suffix, with the remaining functional groups indicated by numbered prefixes, appearing in the name in alphabetical order from first to last. The numbering of the parent alkane is used, as modified, if necessary, by application of the Cahn Ingold Prelog priority rules ("CIP") in the case that ambiguity remains after consideration of the structure of the parent hydrocarbon alone. In IUPAC nomenclature, a number of prefixes, suffixes and infixes are used to describe the type and position of functional groups in the compound.įor many compounds, naming can begin by determining the name of the parent hydrocarbon and by identifying any functional groups in the molecule that distinguish it from the parent hydrocarbon.
