प्रश्न
Name the compound formed when ethanol is heated in excess of conc. sulphuric acid at 443 K. Also, write the chemical equation of the reaction stating the role of conc. sulphuric acid in it. What would happen if hydrogen is added to the product of this reaction in the presence of a catalyst such as palladium or nickel?
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.
