WebInfluence of the solvent in an S N 2 reaction. The rate of an SN2 reaction is significantly influenced by the solvent in which the reaction takes place. The use of protic solvents … WebIn addition to the nucleophile, the solvent also plays a role in determining the major mechanism in nucleophilic substitution reactions. Here, you need to remember that polar aprotic solvents favor the S N 2 mechanism, while polar protic solvents favor the S N 1 mechanism. These two types of solvents are given in the table below.
