WebJan 23, 2024 · In the other (bottom) pathway, methoxide ion acts as a base (rather than as a nucleophile) in an elimination reaction. As we will soon see, the mechanim of this reaction is single-step, and is referred to as the E2 mechanism. In the methanol solvent used here, methanethiolate has greater nucleophilicity than methoxide by a factor of 100. 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.
