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, … WebSo, bulky groups then: tert-butyl would be a good example of a ‘small’ bulky group.
