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

Options

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

Explanation

To determine the relationship between o-cresol and anisole, we can follow these steps:

### Step 1: Identify the Structures
- **o-Cresol**: The structure consists of a phenolic group (a benzene ring with an -OH group) and a methyl group (-CH3) attached to the benzene ring. The IUPAC name for o-cresol is 2-methylphenol.
- **Anisole**: The structure consists of a phenolic group with a methoxy group (-OCH3) attached to the benzene ring. The IUPAC name for anisole is methoxybenzene.

### Step 2: Analyze the Functional Groups
- **Functional Group of o-Cresol**: The presence of the -OH group indicates that o-cresol is classified as an alcohol.
- **Functional Group of Anisole**: The presence of the -OCH3 group indicates that anisole is classified as an ether.

### Step 3: Determine the Relationship
- Since o-cresol (an alcohol) and anisole (an ether) have different functional groups, they are classified as functional isomers. Functional isomers are compounds that have the same molecular formula but differ in the functional groups present.

### Conclusion
The relationship between o-cresol and anisole is that they are functional isomers due to their different functional groups (alcohol vs. ether).
