8.5: Elimination reactions - Chemistry LibreTexts
Alkyl halides undergo elimination via two common mechanisms, known as E2 and E1, which show some similarities to S N 2 and S N 1, respectively. In E2, elimination shows a second order rate law, and occurs in a single concerted step (proton abstraction at C α occurring at the same time as Cβ-X bond cleavage).
Elimination reaction - Wikipedia
An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one- or two-step mechanism. [2] The one-step mechanism is known as the E2 reaction , and the two-step mechanism is known as the E1 reaction .
Elimination Reaction - E1 & E2 Reaction Mechanisms - BYJU'S
An elimination reaction is a reaction in which atoms are removed as molecules or compounds. Elimination is generally catalysed by a metal, an acid or base. Elimination reactions often compete with substitution reactions. In this reaction, a substrate (typically an alkyl halide) eliminates one equivalent (unit) of acid to form an alkene.
