Web24 Jun 2024 · All the chemical reactions we know can be categorized into two groups as concerted reactions and stepwise reactions. The key difference between concerted and stepwise reactions is that concerted reactions are single-step reactions, whereas stepwise reactions are multistep reactions. Reference: 1. “Concerted Reaction.” WebThis type of mechanism involves two steps. 1. The first step is the ionization of alkyl halide in the presence of aqueous acetone or ethyl alcohol 2. The second step is the attack of the nucleophile. S N 1 Reaction Mechanism.
