WebSn2 reactions are quite similar to sn1 reactions: both are types of nucleophilic substitution reactions, resulting in a version of the original reactant with the leaving group substituted for the nucleophile. However, it is important to understand the distinctions between the two, as sn2 reactions have a very different mechanism. WebXie, J., & Hase, W. L. (2016). Rethinking the SN2 reaction.
