Polysilicon hydrides are polymers containing only silicon and hydrogen. They have the formula where 0.2 ≤ n ≤ 2.5 and x is the number of monomer units. The polysilicon hydrides are generally colorless or pale-yellow/ocher powders that are easily hydrolyzed and ignite readily in air. The surfaces of silicon … See more Polysilicon hydrides are much less thermally stable than the corresponding alkanes (CnH2n+2). They are kinetically labile, with their decomposition reaction rate increasing with increases in the number of silicon … See more In addition to the polysilicon halides, another related compound, in which the hydrogen is partially replaced by an inorganic group, is … See more • Polysilicon halides See more When n = 2 in (SiHn)x, the polymer is termed polysilene, which has a quasi-one-dimensional (zigzag) chain structure in which each silicon atom is bonded to two other silicon skeletal atoms and two hydrogen atoms. Thus the Si atom is tetravalent (has … See more When hydrogen atoms in linear polysilene are replaced with organic substituents, particularly alkyl and aryl groups, polysilanes are obtained. Although organosilicon polymers can be … See more WebSaline Hydrides. These are hydrides that form when hydrogen reacts with s-Block elements. These are elements found in Group 1 and Group 2. These alkali metals and alkaline earth metals are more electropositive than …
