WebAlkyl 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 C β-X bond cleavage). In E1, elimination goes via a first order rate law, … WebCHEM 3A. Dr. Pete Marsden 4. ... Provide the appropriate base that leads to the major desired product, ...
