The functional isomers of ethers are

Options

A. ketone
B. aldehyde
C. alcohols
D. esters

Answer

To determine the functional isomers of ethers, we need to understand the definition of functional isomers and the structure of ethers. Here’s a step-by-step solution:

### Step 1: Define Functional Isomers
Functional isomers are compounds that have the same molecular formula but different functional groups. This means they have the same number of atoms of each element but are arranged in such a way that they exhibit different chemical properties due to the presence of different functional groups.

**Hint:** Remember that functional isomers must have the same molecular formula but different functional groups.

### Step 2: Understand the Structure of Ethers
Ethers have the general formula R-O-R', where R and R' can be alkyl or aryl groups. The key feature of ethers is the presence of an oxygen atom bonded to two carbon-containing groups.

**Hint:** Ethers are characterized by the R-O-R' structure.

### Step 3: Identify Possible Functional Isomers
To find the functional isomers of ethers, we look for compounds that have the same molecular formula as ethers but contain different functional groups. The most common functional isomers of ethers are alcohols, which contain a hydroxyl group (-OH).

**Hint:** Focus on functional groups that can be derived from the same molecular formula as ethers.

### Step 4: Compare Ethers and Alcohols
For example, consider dimethyl ether (CH3OCH3) and ethanol (CH3CH2OH). Both compounds have the same molecular formula, C2H6O, but differ in their functional groups: dimethyl ether has an ether functional group, while ethanol has an alcohol functional group.

**Hint:** Use specific examples to illustrate the relationship between ethers and their functional isomers.

### Step 5: Conclude the Functional Isomers of Ethers
Based on the analysis, the functional isomers of ethers are alcohols. Other compounds like esters, ketones, and aldehydes do not qualify as functional isomers of ethers because they have different molecular formulas.

**Hint:** Confirm that the identified functional isomers share the same molecular formula with ethers.

### Final Answer
The functional isomers of ethers are alcohols.
