Silicone
Inorganic Compound of Class 12
Silicones are an interesting group of condensation polymers, formed as a result of the bonding of Si, O and C.
2CH3Cl + Si 
(CH3)2SiCl2
(CH3)2SiCl2 + 2H2O 
(CH3)2Si(OH)2 + 2HCl
R2SiCl2 on hydrolysis gives rise to straight chain polymers.
Repeated condensations result in the formation of macromolecules which are called silicones. Starting with (CH3)2Si(OH)2 the polymers obtained are called silicone oils.
Silicone rubbers are composed of units with very high molecular weights bridged together with ethylene or similar groups.
