E2 Reaction

An E2 reaction is a chemical process where a molecule loses a part—typically a small group like a halogen—and simultaneously forms a new double bond between two carbon atoms. This occurs in a single, concerted step, meaning bonds break and form at the same time. The reaction usually requires a strong base to remove a hydrogen atom that’s attached to a carbon adjacent to the leaving group. E2 reactions are common in organic chemistry for creating alkenes and are influenced by the structure of the molecule and the reaction conditions.
