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.

Element	Electronic configuration
$X$	$1s^2, 2s^2, 2p^2$
$Y$	$1s^2, 2s^2, 2p^6, 3s^1$
$Z$	$1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^{10}, 4s^2, 4p^5$

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