Dehydration of ethanol gives

Options

A. ethane
B. ethanoic acid
C. ethene
D. ether

Explanation

To solve the question regarding the dehydration of ethanol, we will follow these steps:

### Step 1: Understand the Structure of Ethanol
Ethanol is a simple alcohol with the chemical formula C2H5OH. Its structure can be represented as:
\[ \text{CH}_3\text{CH}_2\text{OH} \]

### Step 2: Define Dehydration
Dehydration refers to the process of removing water (H2O) from a compound. In the case of ethanol, we will remove a water molecule from its structure.

### Step 3: Identify the Water Molecule to be Removed
In ethanol, the water molecule can be removed by eliminating the hydroxyl group (-OH) and a hydrogen atom from a neighboring carbon. This results in the formation of a double bond.

### Step 4: Perform the Dehydration Reaction
When we remove a water molecule (H2O) from ethanol, we can visualize the reaction as follows:
1. Remove the -OH group from the ethanol.
2. Remove a hydrogen atom from the adjacent carbon.

This leads to the formation of a double bond between the two carbon atoms.

### Step 5: Write the Product
After the dehydration reaction, the product formed is:
\[ \text{C}_2\text{H}_4 \]
This compound is known as ethene (or ethylene).

### Final Answer
Thus, the dehydration of ethanol gives ethene (C2H4).
