Solution

The correct option is C
Intramolecular dehydration

Ethanol, when heated with excess conc. H₂SO₄ at 443K undergoes intramolecular dehydration (i.e. removal of water within a molecule of ethanol) to give ethene.

${CH}_{3} {C H}_{2} O H Conc . H_{2} S O_{4} - ------ \to 443 K {CH}_{2} = {CH}_{2} + H_{2} O$

Ethanol Ethene
