If the starting material for the manufacture of silicones is $RSiCl_3$,write the structure of the product formed.

(N/A) The hydrolysis of $RSiCl_3$ leads to the formation of a silanetriol,$RSi(OH)_3$,which undergoes polymerization to form a cross-linked silicone polymer.
Step $1$: Hydrolysis
$RSiCl_3 + 3H_2O \rightarrow RSi(OH)_3 + 3HCl$
Step $2$: Polymerization
The silanetriol units undergo condensation polymerization by eliminating water molecules to form a three-dimensional cross-linked structure:
$n RSi(OH)_3 \rightarrow (RSiO_{1.5})_n + 1.5n H_2O$
The resulting structure is a cross-linked polymer where each silicon atom is bonded to an $R$ group and three oxygen atoms,which are shared with other silicon atoms.
