Silicone Polymer Synthesis

The reaction sequence is:

RCl → SiCu powder → R₂SiCl₂ → H₂O → R₂Si(OH)₂ → Condensation → Compound (A)

Description:

RCl reacts with silicon-copper (SiCu) powder to form dichlorosilane (R₂SiCl₂).
R₂SiCl₂ undergoes hydrolysis with water to yield silanol (R₂Si(OH)₂).
Through condensation (dehydration), silanol groups polymerize to form siloxane linkages.

Compound (A) is a polysiloxane or silicone polymer, characterized by repeating -Si-O- units.
