Question
What are silicones? Where are they used?

Answer

i. a. Silicones are organosilicon polymers having $R_2SiO ($where, $R = CH_3 $ or $C_6H_5 $ group$)$ as a repeating unit held together byImage
b. Since the empirical formula $R_2SiO ($where $R = CH_3 $ or $C_6H_5 $ group$)$ is similar to that of ketones $(R_2CO)$, these compounds are named as silicones.
ii. Applications: They are used as
  • insulating material for electrical appliances.
  • water proofing of fabrics.
  • sealant.
  • high temperature lubricants.
  • for mixing in paints and enamels to make them resistant to high temperature, sunlight and chemicals.
