Question

what happens when ethyl alcohol is heated with excess concentrated H2SO4 at 160°C​

Answer 1

Answer:

When ehanol is heated with concentrated sulphuric acid at 443 K, dehydration takes place and ethene is formed. In this reaction concentrated sulphuric acid acts as a dehydrating agent.

Answer 2

Answer:

When ethyl alcohol is heated with excess concentrated H₂SO₄ at 160°C​, it forms ethene.

Explanation:

When alcohols are heated with concentrated H₂SO₄ at 160⁰ C, they undergo dehydration to form an alkene. The process of elimination of water molecules from a compound is called dehydration.

When ethyl alcohol is heated with excess concentrated H₂SO₄ at 160°C​, it undergoes dehydration to form ethene as the end product. The reaction takes place as follows.

CH₃CH₂OH + H₂SO₄ → CH₂=CH₂ + H₂O
