Question

The metal that is used as a catalyst in the synthesis of (CH$_3$)$_2$SiCl$_2$ in Rochow-M\"uller process is _ _ _.

• A. Cu
• B. Zn
• C. Sn
• D. Fe

Hint:

Rochow process: Si + CH$_3$Cl in presence of Cu catalyst gives organosilicon compounds

Answer 1

The Correct Option is A

Step 1: Understand Rochow-M\"uller process.
This process is used for the industrial synthesis of organosilicon compounds, especially dimethyldichlorosilane
It involves the reaction of methyl chloride (CH$_3$Cl) with silicon

Step 2: Role of catalyst.
A metal catalyst is required to facilitate the reaction between silicon and methyl chloride

Step 3: Identify the catalyst.
Copper (Cu) is used as the catalyst in this processIt enhances the formation of (CH$_3$)$_2$SiCl$_2$ as the major product

Step 4: Conclusion.
\[ \boxed{\text{Cu}} \]
