Question

Write the structural formula of ethanol. What happens when it is heated with excess of conc. H2SO4, at 443 K Write the chemical equation for the reaction stating the role of conc h2so4 in this reaction

Answer 1

Hi !

Ethanol -> CH₃CH₂OH

When Ethanol is heated with excess of conc. H₂SO₄, at 443 K , Ethene is formed .
                      conc. H₂SO₄
CH₃CH₂OH ----------------------> CH₂ = CH₂ + H₂O

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

Answer 2

When Ethanol is heated with excess of conc. H₂SO₄, at 443 K , Ethene is formed .

                     conc. H₂SO₄

CH₃CH₂OH ----------------------> CH₂ = CH₂ + H₂O

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

hope it helps.....
