Ethanol can be converted to ethene which can then be changed to ethane.
Choose the correct word or phrase from the brackets to complete the following sentences:
Converting ethanol to ethene requires the use of _______(concentrated hydrochloric acid / concentrated nitric acid/concentrated sulphuric acid)

Explanation

To convert ethanol to ethene, we need to follow a specific chemical process known as dehydration. Here’s a step-by-step solution to the question:

### Step-by-Step Solution:

1. **Identify the Reaction**: We are converting ethanol (C2H5OH) to ethene (C2H4). This process involves the removal of a water molecule (H2O) from ethanol.

2. **Understand Dehydration**: The process of converting an alcohol to an alkene by removing water is called dehydration. In this case, we will remove one hydrogen atom and one hydroxyl group (OH) from ethanol.
