Nucleophilic Substitution Reactions: Mechanisms - CliffsNotes

WebSN1 Reaction Two-step reaction process: 1. carbon-halogen bond breaks, resulting in a positively charged carbon (carbonation), and 2. nucleophile attacks the carbocation, forming a new bond Mostly occurs in tertiary and secondary alkyl halides Unimolecular and follows first-order kinetics WebThe SN2 reaction is a second-order reaction. So, we have to look for the molecule which can undergo an SN2 reaction. The molecule which is less hindered can undergo SN2 reaction easily. The less hindered molecule is a primary alkyl halide without any substituents on it. Here, CH3Br is a primary alkyl halide without any substituents on it.
