S stands for substitution, N for nucleophilic, and the 2 is because the initial stage of the reaction involves two species - the bromoethane and the Nu - ion. If your syllabus doesn't refer to S N 2 reactions by name, you can just call it nucleophilic substitution.

WebJul 20, 2024 · Substitution is completed by proton abstraction (step 2) which re-establishes the aromatic sextet. An important point must be made here: because aromatic π bonds are substantially less reactive than alkene p bonds, the electrophilic must be VERY electrophilic - usually a carbocation.
