Alcohols and ethers are

Options

A. Position isomers
B. Functional isomers
C. Chain isomers
D. Metamers

Explanation

To determine the relationship between alcohols and ethers, we need to analyze their structural differences and similarities. Here’s a step-by-step solution:

### Step 1: Understand the Definitions
- **Isomers**: Compounds that have the same molecular formula but different structural formulas.
- **Functional Groups**: Specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

### Step 2: Identify Alcohols and Ethers
- **Alcohols**: Organic compounds that contain one or more hydroxyl (-OH) groups. For example, ethanol (C2H5OH).
- **Ethers**: Organic compounds that have an oxygen atom bonded to two alkyl or aryl groups. For example, dimethyl ether (CH3OCH3).

### Step 3: Compare Their Functional Groups
- Alcohols have the functional group -OH (hydroxyl group).
- Ethers have the functional group -O- (an oxygen atom between two carbon groups).

### Step 4: Analyze Their Molecular Formulas
- Both alcohols and ethers can have the same molecular formula. For example, ethanol (C2H6O) and dimethyl ether (C2H6O) both have the same molecular formula but different structures.

### Step 5: Classify the Relationship
- Since alcohols and ethers have the same molecular formula but different functional groups, they are classified as **functional isomers**.

### Conclusion
The correct classification is that alcohols and ethers are **functional isomers**.
