Parent hydride

From Wikipedia, the free encyclopedia
(Redirected from Parent hydrocarbon chain)

In chemistry, a parent hydride in IUPAC nomenclature refers to a main group compound with the formula AHn, where A is a main group element. The names of parent hydrides end with -ane, analogous with the nomenclature for alkanes. Derivatives of parent hydrides are named by appending prefixes or suffixes to the name of the parent hydride to indicate the substituents that replace the hydrogen atoms.

Parent hydrides are used in both the organic nomenclature, and inorganic nomenclature systems.[1]
