What is the relation in between o-cresol and anisol :

Options

A. Positional isomer
B. Functional isomer
C. Metamers
D. Chain isomer

Explanation

To understand the relationship between o-cresol and anisole, we can analyze their structures and functional groups.

### Step-by-Step Solution:

1. **Identify the Molecular Formula**:
- Both o-cresol and anisole have the same molecular formula: C7H8O.

2. **Draw the Structures**:
- **o-Cresol**: This compound is a derivative of phenol where a hydroxyl group (-OH) is attached to the benzene ring, and a methyl group (-CH3) is also attached to the benzene ring at the ortho position (adjacent to the -OH group).
- **Anisole**: This compound is a derivative of benzene where a methoxy group (-OCH3) is attached to the benzene ring.

3. **Identify the Functional Groups**:
- In o-cresol, the functional group is a hydroxyl group (-OH), which makes it an alcohol.
- In anisole, the functional group is a methoxy group (-OCH3), which classifies it as an ether.

4. **Compare the Functional Groups**:
- o-Cresol has an alcohol functional group, while anisole has an ether functional group. This difference in functional groups leads to different chemical properties and reactivity.

5. **Conclusion**:
- The relationship between o-cresol and anisole lies in their molecular formula (C7H8O) and the fact that they are both aromatic compounds derived from benzene. However, they differ in their functional groups, which results in different chemical behaviors.
