Nucleophilic Substitution Reactions Lab (SN1 and SN2 reaction mechanisms) Below are my lab results for SN1 and SN2 reactions. This first column of the chart gives the ten starting material halides used in this experiment. The second column gives the reaction time for SN1 mechanisms with silver nitratate in ethanol solution. The third column gives the reaction time for SN2 mechanisms with sodium iodide. In theory, primary alkyl halides are expected to react faster in SN2 mechanisms, and tertiary alkyl...
