WebApr 9, 2024 · Thus, the reactivity of alkyl halides increases in the series: primary < secondary < tertiary. The reaction rate does not depend on the nature and concentration of the nucleophile. The stereochemical result of the reaction is racemization. The reaction may be accompanied by rearrangements of carbocations at an intermediate stage. slowly fast WebAug 18, 2024 · Mechanism of SN1 Reaction. The reaction takes place in two steps. a) Step I: Haloalkanes ionize in the solvent to form a carbocation. b) Step II: Nucleophile attacks the carbocation to give the product. The rate of nucleophilic substitution reaction depends only on the concentration of the substrate and the reaction is of first-order kinetics.
