उत्तर
Ethene is prepared from ethanol by heating it at 443 K with excess concentrated sulphuric acid.
`underset("(ethanol)")("C"_2"H"_5"OH")overset("Conc"."H"_2"SO"_4)(->)underset("(ethene)")("CH"_2 = "CH"_2) + "H"_2"O"`
The concentrated sulphuric acid acts as a dehydrating agent which removes water from ethanol.
