If the starting material for the manufacture of silicones is $RSiCl_{3}$,write the structure of the product formed.
(N/A) The hydrolysis of $RSiCl_{3}$ yields $RSi(OH)_{3}$:
$RSiCl_{3} + 3H_{2}O \longrightarrow RSi(OH)_{3} + 3HCl$
Subsequent condensation of $RSi(OH)_{3}$ units leads to the formation of a cross-linked silicone polymer. The structure involves a repeating unit of $(RSiO_{1.5})_n$. The condensation results in a network structure where each silicon atom is bonded to three oxygen atoms,as shown below:
(Structure: $A$ network of $Si-O-Si$ linkages where each $Si$ atom is attached to one $R$ group and three oxygen atoms,forming a 3D cross-linked polymer.)
