Ans: A nucleophilic substitution will proceed through the SN1, it proceeds through a unimolecular reaction. This means that the rate-determining step of the reaction involves only one molecule (unimolecular). The SN1 is a two step process:
The characteristics of nucleophilic substitution are as follows:
The hydrocarbons such as Haloalkanes and Haloarenes are the ones, in which one or more hydrogen atoms are replaced with halogen atoms. The main difference between Haloalkanes and Haloarenes is that Haloalkanes are derived from open chained hydrocarbons, also called alkanes, and Haloarenes are derived from aromatic hydrocarbons.
