WebVideo transcript. - [Lecturer] Since the SN1 mechanism involves the formation of a carbocation a rearrangement is possible. So let's look at this SN1 reaction. On the left is our alkyl halide, ethanol is our solvent and on the right is our product. The first step should be loss of a leaving group. 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 …
