How would bring about the following conversions ? Name the process and write the reaction involved.
ethanol to ethene.

Explanation

To convert ethanol (C2H5OH) to ethene (C2H4), we can use the process of dehydration. The reaction involves the removal of a water molecule from ethanol, resulting in the formation of ethene. Here’s a step-by-step breakdown of the conversion:

### Step 1: Identify the Reactant and Product
- **Reactant**: Ethanol (C2H5OH)
- **Product**: Ethene (C2H4)

### Step 2: Choose the Reagent
To carry out the dehydration of ethanol, we will use concentrated sulfuric acid (H2SO4) as the dehydrating agent.
