what are silicones . preparation of silicones​

Answer 1

Answer:

1. Silicones are a type of synthetic polymer, a material made of smaller, repeating chemical units called monomers that are bonded together in long chains.

2. The preparation of silicones is carried out by the hydrolysis of dialkyldichlorosilanes or diaryldichlorosilanes. These dichlorosilanes are prepared by passing the vapours of RCl or ArCl over silicon at 570K with the catalyst copper.
