The catalyst used in kharash reaction, is -

Options

A. Only halogenated compound
B. Any peroxide
C. `Al_(2)(SO_(4)_(3)`
D. `TiCl_(4)`

Answer

### Step-by-Step Solution:

1. **Understanding the Kharash Reaction**:
The Kharash reaction involves the radical oxidation of allylic alkenes. It is a specific type of reaction that leads to the formation of products through the action of radicals.

2. **Identifying the Catalyst**:
In the Kharash reaction, the catalyst used is a peroxide. Peroxides are compounds that contain a peroxy linkage (–O–O–).

3. **Specific Catalyst**:
The specific catalyst mentioned in the context of the Kharash reaction is **t-butyl peroxybenzoate**. This is a type of peroxide that is commonly used to initiate radical reactions.

4. **Conclusion**:
Therefore, the catalyst used in the Kharash reaction is t-butyl peroxybenzoate.

### Final Answer:
The catalyst used in the Kharash reaction is **t-butyl peroxybenzoate**.
