Solvent effects on sn1 and sn2 reactions

WebAug 11, 2015 · The higher the temperature, the faster a non-biological reaction tends to occur. For SN 1 and SN 2 reactions, the higher the temperature, the more elimination products you get. The more elimination products you get, since the amount of reactant is limited, the less substitution products you get, as well. This is because the activation … WebIn an SN2 reaction, the rate law is 2nd order. That is, the reaction rate depends on the concentrations of two components, the alkyl halide and the nucleophile. Hence the term Substitution Nucleophilic 2nd order. The 1 in SN1 and the 2 in SN2 come from the kinetics of the reactions, not from 1° and 2°. Hope this helps.

Summary of Solvent Effects on Nucleophilic Substitution Reactions

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.
