The following is aryl alkyl halide

Options

A. o - chloro toluene
B. o - bromo chloro benzene
C. 1 - chloro - 2 - phenyl ethane
D. toluene

Explanation

To determine which compound is an aryl alkyl halide among the given options, we need to understand the definitions of aryl, alkyl, and halide groups.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Aryl Group**: This is a functional group derived from an aromatic ring (like benzene). It is represented as Ar.
- **Alkyl Group**: This is a group derived from alkanes, represented as R, which consists of carbon and hydrogen atoms.
- **Halide**: This refers to a halogen atom (F, Cl, Br, I) that replaces a hydrogen atom in an alkane or an aryl compound.

2. **Analyzing Each Option**:
- **Option A: Ortho-Chloro-Toluene**:
- Toluene has a benzene ring (an aryl group) with a methyl group (an alkyl group) and a chlorine atom (a halide).
- This compound is classified as an aryl halide, not an aryl alkyl halide because the halide is attached to the aryl group.

- **Option B: Ortho-Bromo-Chlorobenzene**:
- This compound consists of a benzene ring with two halogens (bromine and chlorine).
- There is no alkyl group present, so this cannot be classified as an aryl alkyl halide.

- **Option C: 1-Chloro-2-Phenyl-2-Ethane**:
- This compound has a phenyl group (an aryl group) and a chloro group (a halide) attached to an ethane backbone (which is an alkyl group).
- Here, the halide is attached to the alkyl part, making this an aryl alkyl halide.

- **Option D**: (Not provided in the transcript, but we can assume it does not fit the criteria based on the analysis of the other options).

3. **Conclusion**:
- After analyzing all options, **Option C: 1-Chloro-2-Phenyl-2-Ethane** is the only compound that fits the definition of an aryl alkyl halide.

### Final Answer:
**Option C: 1-Chloro-2-Phenyl-2-Ethane is the aryl alkyl halide.**
