The SN2 reaction is a type of reaction mechanism that is common in organic chemistry. In this mechanism, one bond is broken and one bond is formed in a concerted way, i.e., in one step. The name SN2 refers to the Hughes-Ingold symbol of the mechanism: "SN" indicates that the reaction is a nucleophilic substitution, and "2" that it proceeds via a bi-molecular mechanism, which mea… WebJan 23, 2024 · The corresponding designation for the elimination reaction is E2. An energy diagram for the single-step bimolecular E2 mechanism is shown on the right. We should be aware that the E2 transition state is less well defined than is that of S N 2 reactions. More bonds are being broken and formed, with the possibility of a continuum of states in ...

WebThe SN2 reaction is a type of nucleophilic substitution in which an electron-rich nucleophile displaces the halogen atom bonded to the central carbon of an alkyl halide molecule. The halide ion that is displaced from the carbon atom is called the leaving group. SN2 reaction takes place at the site of a saturated carbon atom.
