Silicone is a polymer of A. Tetraalkyl silane B. Silicon tetrachloride C. Dialkyl dichloro silane D. Silane

Tetraalkyl silane
Silicon tetrachloride
Dialkyl dichloro silane
Silane

The correct answer is: D. Silane

A silane is a compound with the general formula $R_nSiH_4$, where $R$ is an alkyl or aryl group. Silanes are the simplest members of the silicone family, and they are used as precursors to silicone polymers.

Silicon tetrachloride is a compound with the formula $SiCl_4$. It is a colorless, fuming liquid that is used as a precursor to silicones.

Dialkyl dichloro silane is a compound with the formula $R_2SiCl_2$. It is a colorless, flammable liquid that is used as a precursor to silicones.

Tetraalkyl silane is a compound with the formula $R_4Si$. It is a colorless, flammable liquid that is used as a precursor to silicones.

Silicones are a family of polymers that are made from silanes. They are characterized by their high thermal stability, chemical inertness, and electrical insulation properties. Silicones are used in a wide variety of applications, including sealants, adhesives, lubricants, and cosmetics.
