Question

What are silicones ? how are they prepared ? give with a suitable reaction .

Answer 1

any of a class of synthetic materials which are polymers with a chemical structure based on chains of alternate silicon and oxygen atoms, with organic groups attached to the silicon atoms. Such compounds are typically resistant to chemical attack and insensitive to temperature changes and are used to make rubber and plastics and in polishes and lubricants.

Answer 2

Silicones are organo silicons which are synthetic polymer containing repeated units of R₂SiO and are held together by Si-O-Si.

Preparation of Silicones are done by Silicon Chlorides, then polymerised to form Silicones.

The reaction is quite difficult to draw here.
