Write the structural formula of ethanol. What happens when it is heatedwith excess o conc. H2So4 at 443 K? Write the chemical equation for thereaction stating the role of conc. HoSO4 in this reaction.

Answer»

Ethanol -> CH₃CH₂OH

When Ethanolis heated with excess of conc. H₂SO₄, at 443 K , Ethene is formed . conc. H₂SO₄CH₃CH₂OH ----------------------> CH₂ = CH₂ + H₂O

H₂SO₄ acts as a dehydrating agent , that removes water molecule from ethanol
