Question

Silicone's are synthetic polymers containing repeated $R_{2}SiO$ units.

• A. True
• B. False

Answer 1

The correct option is A True

SILICONES: Organic polymers containing silicon in them are called as silicones. These are organosilicon polymers containing $R_{2}SiO$ repeating units and empirical formula analogous to ketone $\left(R_{2}CO\right)$.
Alkyl substituted : These are formed by hydrolysis of alkyl chlorosilanes and their polymerisation. The alkyl or aryl substituted chlorosilanes are prepared by the reaction of Grignard reagent and silicon tetrachlorides.
