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 <a href="r93_185.htm">Table 2</a>). 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 <a href="r93_131.htm">R-1.1</a>, the name of the hydrides is modified by affixing a <img src="./images/bm2560.gif"> symbol as instructed by <a href="r93_131.htm">R-1.1</a>. <p> <DL><DT><B><I>See Also:</I></B><br><DD> <a href="r93_181.htm">R-2.0 Introduction</a><br> <a href="r93_183.htm">R-2.2 Acyclic Polynuclear Hydrides</a><br> <a href="r93_201.htm">R-2.3 Monocyclic Hydrides</a><br> <a href="r93_228.htm">R-2.4 Polycyclic Parent Hydrides</a><br> <a href="r93_271.htm">R-2.5 Substituent Prefix Names Derived from Parent Hydrides</a><br> </DL> <hr><a href="../"><img src="./images/rnd2tc_s.gif" border=0></a><a href="r93_183.htm"><img src="./images/rnd2nx_s.gif" border=0></a> <a href="../SearchNomenclature.php"><img src="./images/search.gif" border=0 alt="search"></a><HR><FONT SIZE="-2" COLOR="Maroon">This HTML reproduction is as close as possible to the published version [see <B>IUPAC, Commission on Nomenclature of Organic Chemistry.</B> <i>A Guide to IUPAC Nomenclature of Organic Compounds (Recommendations 1993)</i>, 1993, Blackwell Scientific publications, Copyright 1993 IUPAC].
