Rascing's process is employed for the commerical preparation of:

Options

A. Ehthyl chloride
B. Grignard's regent
C. Chlorobenzane
D. Ethanol

Explanation

**Step-by-Step Solution:**

1. **Understanding Raschig's Process**: Raschig's process is a well-known industrial method used for the preparation of certain organic compounds. It is essential to identify what this process specifically produces.

2. **Identifying the Product**: The primary product of Raschig's process is chlorobenzene. This is a compound formed when benzene reacts with hydrogen chloride in the presence of oxygen and a catalyst.

3. **Writing the Reaction**: The chemical reaction for Raschig's process can be represented as follows:
\[ \text{Benzene} + \text{HCl} + \text{O}_2 \xrightarrow{\text{COCl}_2, 500 \text{ K}} \text{Chlorobenzene} + \text{H}_2\text{O} \]
This equation shows that benzene reacts with hydrogen chloride and oxygen to produce chlorobenzene and water.

4. **Conclusion**: Based on the above information, we can conclude that Raschig's process is employed for the commercial preparation of chlorobenzene.

5. **Final Answer**: Therefore, the answer to the question is chlorobenzene.
