उत्तर
The compound that is formed when ethanol is heated in excess of conc. sulphuric acid at 443 K is ethene.
The concentrated sulphuric acid acts as a dehydrating agent in this reaction. It facilitates the removal of a molecule of water from the ethanol molecule.
When hydrogen is added to ethene in the presence of a catalyst such as palladium or nickel, saturation of the compound takes place to form ethane.
