How is ethane prepared from ethanol ? Give the reaction involved in it .

Explanation

To prepare ethene from ethanol, we need to carry out a dehydration reaction. Here’s a step-by-step explanation of the process:

### Step 1: Understanding the Reactant
Ethanol (C2H5OH) is the starting compound. It consists of a two-carbon chain with a hydroxyl (-OH) group.

### Step 2: Setting Up the Reaction Conditions
To convert ethanol to ethene, we need to heat ethanol in the presence of a strong acid, such as concentrated sulfuric acid (H2SO4). The acid acts as a catalyst for the dehydration process.
