Solution

The conversion of ethanol to ethene by the action of concentrated sulphuric acid is an example of dehydration.

Here's the step by step process:

  1. Ethanol (C2H5OH) reacts with concentrated sulphuric acid (H2SO4), which acts as a dehydrating agent.

  2. The sulphuric acid removes a molecule of water (H2O) from the ethanol. This is why it's called a dehydration reaction.

  3. The removal of water results in the formation of ethene (C2H4), along with the water molecule.

So, the correct answer is dehydration.
