Which of the following would increase the proportion of a substitution reaction that proceeds via a SN2 mechanism, rather than SN1? (choose all correct answers) Group of answer choices Use a less reactive nucleophile. Use a more highly substituted alkyl halide. Increase the concentration of the alkyl halide. Increase the concentration of the nucleophile
Draw the major, neutral organic product obtained if: the reaction proceeds by the SN1 mechanism the reaction proceeds by the SN2 mechanism
Draw the major, neutral organic product obtained if: the reaction proceeds by the SN1 mechanism the reaction proceeds by the SN2 mechanism. Draw the major, neutral organic product for each substitution reaction below. (For this question, assume that each substitution reaction goes to completion. Disregard elimination.)

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...
