Parent structure
In the IUPAC nomenclature of chemistry, a parent structure, parent compound, parent name, or simply parent is the denotation for a compound consisting of an unbranched chain of skeletal atoms (not necessarily carbon), or consisting of an unsubstituted monocyclic or polycyclic ring system. [1] Parent structures bearing one or more functional groups that are not specifically denoted by a suffix are called functional parents.[2] Names of parent structures are used in IUPAC nomenclature as basis for systematic names.
A parent hydride is a parent structure with one or more hydrogen atoms. Parent hydrides have a defined standard population of hydrogen atoms attached to a skeletal structure. Parent hydrides are used extensively in organic nomenclature, but are also used in inorganic chemistry.[3]
To construct a systematic name, affixes are attached to the parent name, which denote substituents that replace hydrogen.
