Question

Silicones has the general formula:

• A. $Si{O}_4^{4-}$
• B. $S{i}_2{O}_7^{6-}$
• C. $(R_{2}SiO{)}_n$
• D. $(Si{O}_3{)}_n^{2-}$

Answer 1

The correct option is C $(R_{2}SiO{)}_n$

Synthetic organosilicon compounds having repeated $R_{2}SiO$ units held by $Si–O–Si$ linkages. These compounds have the general formula $(R_{2}SiO{)}_n$ where R = alkyl or aryl group.
