Vedclass · Answer

(A) The hydrolysis of $R_2SiCl_2$ yields dialkyl silanediol,$R_2Si(OH)_2$.Upon condensation (polymerization),these silanediol units eliminate water molecules to form a linear polymeric chain with alternating silicon and oxygen atoms,known as a linear silicone.The reaction sequence is:$RCl$ $\xrightarrow[Si]{Cu 	ext{ powder}} R_2SiCl_2$ $\xrightarrow{H_2O} R_2Si(OH)_2$ $\xrightarrow{	ext{condensation}} -(O-SiR_2)_n-$Therefore,compound $(A)$ is a linear silicone.

$RCl$ $\xrightarrow[Si]{Cu \text{ powder}} R_2SiCl_2$ $\xrightarrow{H_2O} R_2Si(OH)_2$ $\xrightarrow{\text{condensation}} A$
Compound $(A)$ is:
