Q. Read the following write-ups and answer the questions at the end of it Silicones are synthetic polymers containing repeated $R_2 S i O$ units. Since, the empirical formula is that of a ketone $\left(R_2 CO \right)$, the name silicone has been given to these materials. Silicones can be made into oils, rubbery elastomers and resins. They find a variety of applications because of their chemical inertness, water repelling nature, heat-resistance and good electrical insulating property
