SN1 and SN2 reactions are fundamental building blocks to understanding mechanisms in organic chemistry. Kinetic studies for teaching labs have been done on SN1 and SN2 reactions, however, this study is to be used as a quantitative study of initial rates. Using MeasureNet, a system capable of rapidly collecting data from different instruments, a graph of Time Vs. Ion Concentration can be generated. To ensure the reactions would meet the time constraints of a four-hour organic chemistry laboratory session, the reaction conditions were observed using proton NMR to calculate percent completion. When optimal reaction conditions had been established the reactions were measured using ion sensitive probes (bromide and chloride ion probes). Studies of multiple substrates, temperatures, reaction times, and leaving groups will be presented as well as representative student data.
