REAC 714 Studying SN1 and SN2 Reactions: Nucleophilic Substitution at Saturated Carbon
Date of Experiment: February 6, 2008
Objective:
The objective of this laboratory experiment is to study both SN1 and SN2 reactions. The first part of the lab focuses on synthesizing 1-bromobutane from 1-butanol by using an SN2 mechanism. The obtained product will then be analyzed using infrared spectroscopy and refractive index. The second part of the lab concentrates on how different factors influence the rate of SN1 reactions. The factors that will be examined are the leaving group, Br – versus Cl-; the structure of the alkyl group, 3◦ versus 2◦; and the polarity of the solvent, 40 percent 2-propanol versus 60 percent 2-propanol.
Discussion/Theory/Reaction Mechanisms
SN2 Reaction Mechanism:
This reaction takes place by an SN2 mechanism. The reaction must be carried out in a very acidic solution because the......
