The family to which Methoxyethene belongs is

Options

A. Hydrocarbon
B. Ketone
C. Unsaturated ether
D. Ester.

Explanation

To determine the family to which Methoxyethene belongs, we can follow these steps:

### Step 1: Identify the Structure of Methoxyethene
Methoxyethene has the molecular formula CH3O-CH=CH2. It consists of an ether functional group (methoxy, CH3O-) attached to a carbon-carbon double bond (ethene).

### Step 2: Analyze the Functional Groups
In Methoxyethene, we see:
- The presence of an ether group (R-O-R') where R is a methyl group (CH3) and R' is a vinyl group (CH=CH2).
- The presence of a carbon-carbon double bond indicates that it is unsaturated.

### Step 3: Classify the Compound
Given the presence of both the ether functional group and the carbon-carbon double bond, Methoxyethene can be classified as an unsaturated ether.

### Step 4: Review the Options
The options provided were:
1. Hydrocarbon
2. Ketone
3. Unsaturated ether
4. Ester

Since Methoxyethene contains an ether functional group and is unsaturated due to the double bond, it fits the definition of an unsaturated ether.

### Conclusion
Therefore, the family to which Methoxyethene belongs is **unsaturated ether**.
