In this mechanism, one bond is broken and one bond is formed synchronously, i.e., in one step. S N 2 is a kind of nucleophilic substitution. nucleophilic substitution.

WebIn 1935, Edward D. Hughes and Sir Christopher Ingold studied nucleophilic substitution reactions of alkyl halides and related compounds. They proposed that there were two main mechanisms at work, both of them competing with each other. The two main mechanisms are the S N 1 reaction and the S N 2 reaction. WebA Hughes–Ingold symbol describes various details of the reaction mechanism and overall result of a chemical reaction. [1] For example, an S N 2 reaction is a substitution reaction ("S") by a nucleophilic process ("N") that is bimolecular ("2" molecular entities involved) in its rate-determining step.
