organic silicon compounds called silicone. Carbon and silicon cycle in the same table IVA clan, the formation of organic C-Si bonding compounds and C-C bond is quite similar compounds, including : silane. Formula Si_nH_{2n +2} . As a silane, B silane ... halogenated silane, such chlorosilane (R₃SiCl), in which R is alkyl; A silicon alkyl compounds, silicon and alkyl combination; Silicon alcohol, formula R₃SiOH, can generate similar ether compounds : R₃Si-O-SiR₃. There silicon esters. Silicon alcohol ether generated by the reaction of condensation easily generate more in varying degrees of polyether, such as silicone oil is not volatile liquid temperature impact on small, water-resistance, nontoxic no bubble, no oxidation, the oil pump for quality, quality lubricants, resin sealing, waterproofing agents; Polycondensation high level and can be used as insulation resistance the hot resin. And organic carbon compounds are different silicone molecules of silicon-silicon atoms have only one button, no double bond and three keys.
