In IUPAC nomenclature, a parent hydride is a main group compound with the formula AHn, where A is a main group element. The names of parent hydrides are ending 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.

Reactions and structure
Parent hydrides are useful reference compounds, but many are nonexistent or unstable. Group III parent hydrides exist only under extraordinary conditions. Borane dimerizes irreversibly. Gallane and heavier congeners polymerize, sometimes with loss of hydrogen. Plumbane and bismuthane are unstable. For group V, stibane, indane, thallane are also unstable.
