Elimination Reactions (E1, E2)

Subject: Chemistry

Book: General Chemistry

Elimination reactions remove atoms or groups from adjacent carbons to form a double bond. E2 is a one-step, concerted mechanism requiring a strong base. E1 involves a carbocation intermediate after the leaving group departs, making it more common with tertiary substrates. Stereochemistry (anti-periplanar alignment in E2) influences the reaction outcome. Elimination competes with substitution and is crucial in producing alkenes and alkynes.
