Ether and alcohol are _______ isomers.

Explanation

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

### Step-by-Step Solution:

1. **Understand Isomers**:
- Isomers are compounds that have the same molecular formula but different structural formulas.
- They can differ in the arrangement of atoms, types of bonds, or functional groups.

2. **Identify Ethers and Alcohols**:
- Ethers have the general structure R-O-R', where R and R' are alkyl groups.
- Alcohols have the general structure R-OH, where R is an alkyl group.

3. **Compare Functional Groups**:
- Ethers contain an oxygen atom bonded to two alkyl groups (R-O-R').
- Alcohols contain a hydroxyl group (-OH) bonded to an alkyl group (R-OH).
- Since the functional groups are different (ether vs. alcohol), they are classified differently.

4. **Check Molecular Formula**:
- Both ethers and alcohols can have the same molecular formula. For example, dimethyl ether (CH3-O-CH3) and ethanol (CH3-CH2-OH) both have the molecular formula C2H6O.

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

### Final Answer:
Ether and alcohol are **functional isomers**.
