Definition of SILANE
: any of various compounds of hydrogen and silicon that have the general formula SinH2n+2 and are analogous to alkanes
Origin of SILANE
International Scientific Vocabulary silicon + methane
First Known Use: 1916
Any of a series of inorganic compounds of silicon and hydrogen with covalent bonds and the general chemical formula SiH. Silanes are structural analogs of saturated hydrocarbons (seesaturation; alkane) but are much less stable. All burn or explode when exposed to air and react readily with halogens or hydrogen halides to form halogenated silanes and with olefins to form alkylsilanes, products used as water repellents and as starting materials for silicones.
