Parent Hydrides

R-2.1 Mononuclear Hydrides

The names of mononuclear hydrides of the elements for use as parents in substitutive nomenclature are given in Table 2. Many are formed systematically by combining the 'a' term of the element (with elision of the terminal "a") with the ending "-ane", for example, borane for BH3, silane for SiH4, etc. There are important exceptions: methane for CH4, oxidane for OH2, sulfane for SH2, selane for SeH2, etc., (see Table 2). The systematic alternatives to well established common names, e.g., azane for ammonia, oxidane for water, and chlorane, bromane, etc., for hydrogen chloride, bromide, etc., are necessary for naming some derivatives and for generating names of polynuclear homologues. If the bonding number of the element differs from the normal one as defined in R-1.1, the name of the hydrides is modified by affixing a symbol as instructed by R-1.1.
