Elimination Reactions of Alcohols (AQA A-Level Chemistry): Flashcards

Removal of small molecule, forming double bond

Water ($H_2O$)

170°C

Conc. $H_2SO_4$ or $H_3PO_4$

Ethene

Protonation of -OH by acid (makes better leaving group)

Water leaves, carbocation forms

H removed from adjacent carbon, double bond forms

Multiple products (double bond in different positions)

Addition polymers (sustainable alternative to crude oil)
