When ethanol is taken and temperature is kept 170°C. On dehydration with concentration H2SO4 it gives a molecule of _____?
Answer: Ethene
Explanation
At 170°C, ethanol undergoes acid-catalyzed dehydration to form ethene (C₂H₄).
Concentrated H₂SO₄ acts as a dehydrating agent, removing water from ethanol.
