Question

Which of the following is the correct statement about silicones?

• A. They are made up of $Si{O}_4^{4-}$ units.
• B. They are polymers made up of $R_{2}SiO$ units.
• C. They are water soluble compounds.
• D. They are hydrophillic in nature.

Answer 1

Answer: (B)

They are polymers made up of $R_{2}SiO$ units.

Answer:- (B) They are polymers made up of ${\left(R_{2}SiO\right)}_n$ units.

Silicones are polymers which contains ${\left(R_{2}SiO\right)}_n$ chains, where R is any alkyl or phenyl group, present with each silicon atom. They are hydrophobic in nature.
