What are silicones?
उत्तर
- Silicones are organosilicon polymers having R2SiO (where R = CH3 or C6H5 group) as a repeating unit held together by \[\begin{array}{cc}\phantom{}|\phantom{.....}|\\\ce{-Si{-}O{-}Si-}\\|\phantom{.....}|\end{array}\] linkage.
- Since the empirical formula R2SiO (where R = CH3 or C6H5 group) is similar to that of ketones (R2CO), these compounds are named silicones.
