The class of chemical compounds

Silanes are saturated chemical compounds, which means that they consist of one or multiple silicones atoms linked to each other or one or multiple atoms of other chemical elements as the tetrahedral centers of multiple single bonds. By definition, cycles are excluded, so that the silanes comprise a homologous series of inorganic compounds with the general formula. Commercially available silanes are synthetically derived.

Each silicon atom has four bonds, and each hydrogen atom is joined to a silicon atom . A series of linked silicon atoms is known as the silicon skeleton or silicon backbone. The number of silicon atoms is used to define the size of the silane.

Related to silanes, is a homologous series of functional groups, side-chains or radicals with the general formula. Examples include silyl and disilanyl.

The simplest possible silane (the parent molecule) is silane, SiH
4. There is no limit to the number of silicon atoms that can be linked together, the only limitation being that the molecule is acyclic, is saturated, and is a hydrosilicon.

Silanes are very reactive and have moderate biological activity.
