Hydridosilanes
Hydridosilanes are a class of chemical compounds that contain silicon-hydrogen (Si-H) bonds, often in addition to silicon-silicon (Si-Si) bonds and potentially other substituents. They are silicon analogs of hydrocarbons, where silicon atoms are bonded to hydrogen atoms. The simplest hydridosilane is monosilane, SiH4, which is a gas. Higher hydridosilanes, such as disilane (Si2H6), trisilane (Si3H8), and so on, are also known, forming a homologous series similar to alkanes. These compounds are generally less stable than their carbon counterparts and can be pyrophoric, igniting spontaneously in air.
The Si-H bond is polar, with silicon being slightly electropositive and hydrogen slightly electronegative. This polarity
