Question:medium

Consider the following sequence of reactions. \( 2\text{CH}_3\text{Cl} + \text{Si} \xrightarrow[\text{573 K}]{\text{Cu}} X \xrightarrow{\text{H}_2\text{O}} Y \xrightarrow{\text{Polymerization}} Z \). The repeating structural unit in Z is

Show Hint

The synthesis of silicones follows this general path: 1. Rochow Process: \(R-Cl + Si \rightarrow R_nSiCl_{4-n}\) (mainly \(R_2SiCl_2\)). 2. Hydrolysis: \(R_2SiCl_2 + H_2O \rightarrow R_2Si(OH)_2\) (a silanediol). 3. Polymerization: The silanediol molecules condense, eliminating water to form \(-[R_2Si-O]-\) chains. The number of chlorine atoms in the initial silane determines the structure (2 for linear chains, 3 for cross-linking, 1 for chain termination).

\( -[\text{O}-\text{CH}_3\text{Si(O-)}]- \)
\( -[(\text{CH}_3)_2\text{Si-O}]- \)
\( -[\text{O}-\text{Si(CH}_3\text{)-O}]- \) with another CH3 attached to Si
\( -[\text{CH}_2-\text{Si(CH}_3\text{)-O}]- \) with another CH3 attached to Si
