CHEM 2071-007MACKENZIE WILLIAMSON 142JUAN HUEXPERIMENT 6: UNIMOLECULAR AND BIMOLECULAR NUCLEOPHILICSUBSTITUTION REACTIONS DAY 1
CONCLUSIONSNucleophilic substitution reactions occur when a nucleophile attaches to an electrophile and a leaving group on the electrophile leaves and attaches to a new substance. There are two main types of nucleophilic substitution reactions that can occur; SN2 and SN1 reaction. The S and N letters represent nucleophilic substitution, but the different numbers tell how many steps are happening in each reaction. For SN2 reactions, a bond is broken and a new bond is formed in one step. For SN1, reactions happen with one step occurring at a time. Another way to think about whether a reaction will be SN1 or SN2 is to think about the reaction rate equation. For SN1 reactions, only the substrate and the nucleophile affect the rate of the reaction. On day one of thislab we synthesize t-amyl Chloride (2-chloro-2-methylbutane). This mechanism ends up being SN1. This is a three step mechanism. First the acid (HCl) protonates the alcohol to form a good
