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: What the process does.
The Rochow process makes methylchlorosilanes by passing methyl chloride over silicon.

Step 2: Need for a catalyst.
A metal is added to help silicon react with methyl chloride and to favour the dimethyl product.

Step 3: Identify it.
Copper is the catalyst used to give (CH$_3$)$_2$SiCl$_2$ as the main product.

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