Structural formula of ethanol `H-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-OH`
When it is heated with excess of conc .`H_(2)SO_(4)` at 443 K , it undergoes dehydration to form alkene .
`underset("Ethanol")(CH_(3))CH_(2)OHunderset(443K)overset(H_(2)SO_(4))tounderset("Ethene")(CH_(2))=CH_(2)+H_(2)O`
