Which of the following compounds can be classified as aryl halides ?

Options

A. `p-ClC_(6)H_(4)CH_(2)CH(CH_(3))_(2)`
B. `p-CH_(3)CHCl(C_(6)H_(4))CH_(2)CH_(3)`
C. `o-BrH_(2)C-C_(6)H_(4)CH(CH_(3))CH_(2)CH_(3)`
D. `C_(6)H_(5)`-Cl

Explanation

To determine which of the given compounds can be classified as aryl halides, we need to understand the definition of aryl halides. Aryl halides are compounds where a halogen atom (like Cl, Br, etc.) is directly bonded to an aromatic ring, such as a benzene ring.

Let's analyze the options step by step:

### Step 1: Identify the Structures
1. **Option 1**: Para-chloro compound with a benzene ring, where chlorine is attached to the benzene at the para position relative to a CH2 group.
2. **Option 2**: A compound with a benzene ring, where chlorine is attached to a carbon that is not directly part of the benzene ring (it is attached to a CH group).
3. **Option 3**: A compound with a benzene ring where bromine is attached to a carbon adjacent to the benzene ring (CH2Br).
4. **Option 4**: A compound with a benzene ring, where chlorine is directly attached to the benzene ring.

### Step 2: Classify Each Compound
- **Option 1**: The chlorine is directly attached to the benzene ring. **This is an aryl halide.**
- **Option 2**: The chlorine is attached to a carbon that is not part of the benzene ring. **This is not an aryl halide.**
- **Option 3**: The bromine is attached to a carbon adjacent to the benzene ring. **This is not an aryl halide.**
- **Option 4**: The chlorine is directly attached to the benzene ring. **This is an aryl halide.**

### Step 3: Conclusion
Based on the analysis:
- **Aryl halides identified**: Option 1 and Option 4.

### Final Answer:
The compounds that can be classified as aryl halides are **Option 1 and Option 4**.
