WebThe main difference between the E1 and E2 reactions is their number of steps. The E1 reaction takes place in two steps and has a carbocation intermediate. In contrast, the E2 reaction takes place in one step and has no intermediate. Thus, E1 is a first-order reaction, while E2 is a second-order reaction requiring an anti periplanar geometry WebSn1, Sn2, E1, and E2 reactions form the basis for understanding why certain products are more likely to form than others. We will learn about the reaction mechanisms, and how nucleophilicity and electrophilicity can be used to choose between different reaction pathways. Free radical reaction. bity wera
