Give an example of the process which demonstrates the dehydrating nature of concentrated sulphuric acid. 

Explanation

### Step-by-Step Solution:

1. **Identify the Substance**: The example we will use to demonstrate the dehydrating nature of concentrated sulfuric acid is sucrose (C₁₂H₂₂O₁₁), commonly known as sugar.

2. **Reaction Setup**: When concentrated sulfuric acid (H₂SO₄) is added to sugar, it acts as a dehydrating agent. This means it will remove water (H₂O) from the sugar.

3. **Chemical Reaction**: The chemical reaction can be represented as follows:
\[
