Question

Which of the following gives linear chain silicones on polymerisation by controlled hydrolysis?

(a) Dimethyl silicon chloride

(b) Trimethyl silicon chloride

(c) Tetramethyl silicon chloride

(d) Momethyl silicon chloride

This question was posed to me in an internship interview.

This interesting question is from Silicones and Polymeric Composites in portion Polymers of Engineering Chemistry I

Answer 1

Right answer is (a) Dimethyl silicon chloride

For explanation: Dimethyl silicon chloride gives linear chain silicones on polymerisation by controlled hydrolysis. All the other options does not give such type of reaction.
