The reaction of methyl chloride with silicon at 573 K in the presence of copper as a catalyst produces substitued chlorosilanes. Hydrolysis of chlorosilanes produces silanols. The silanols with appropriate substitution, thus formed, are used to make silicone polymers. The correct statement in this context is:

Options

1. AOnly two different chlorosilanes are produced in the reaction of methyl chloride with silicon.
2. BA silicate is formed on condensation polymerization of silanols.
3. CThe chain length of the silcone polymer can be controlled by adding trimethylchlorosilane.
4. DTrimethylsilanol upon condensation yields a straight chain polymer.
