13/01/2017В В· The Sn2 reaction is a second order nucleophilic substitution reaction where the rate is dependent on the concentration of the substrate / alkyl halide and the nucleophile. SN2 reactions occur with Bimolecular nucleophilic substitution, or S N 2 reaction, and unimolecular nucleophilic substitution , or S N 1 reaction. In an S N 2 reaction, the reaction rate depends on the concentrations of both starting products, as well as that of the substrate and nucleophile.

One such reaction is shown below. During the reaction, the phenyl group remains the same and so does the CH 2 group, but the Cl group is replaced by the PhS group. The reaction occurs at the CH 2 group, so the reaction is a 'nucleophilic substitution at a saturated carbon atom'. The use of nucleophilic substitution is being studied in the unimolecular reaction, S N 1, and bimolecular reaction, S N 2. 2 Nucleophilic substitution is a type of reaction where an electron nucleophile bonds or attracts a positive or partially positive charge that is on an atom or set of atoms known as the leaving group; aside from the leaving group, the positive or partially positive atom
