Question

Silicone oil is obtained from the hydrolysis and polymerisation of

• A. trimethylchlorosilane and dimethydichlorosilane
• B. trimethylchlorosilane and methylrichlorosilane
• C. methyltrichlorosilane and dimethyldichlorosilane
• D. triethylchlorosiland and diethyldichlrosilane

Answer 1

Answer: (A)

trimethylchlorosilane and dimethydichlorosilane

Answer 2

Silicone oils are formed on low degree of polymerisationSilicon oil in a polymer of trimethylchloro silane and dimethyldichloro silane. These
are useful as broad spectrum antifoaming agents.
