1. Compare the reactivity of primary alkyl halides in part 1 (SN2) of this experiment to the reactivity of primary alkyl halides today. What conclusions, if any, can you make about the reactivity of these molecules under these different conditions? Use specific data to make your point. 2. Compare the reactivity of secondary alkyl halides in part 1 (SN2) of this experiment to the reactivity of secondary alkyl halides today. What conclusions, if any, can you make about the reactivity...

In this exercise, you will use two reagent mixtures to test a variety of organic halides. The distinct differences in the factors affecting the SN2 and SN1 mechanisms make it possible to determine which mechanism is favored by a given compound. One reagent and solvent favors SN2 reactivity, the other SN1 reactivity. From the results of your tests, you will determine which mechanism, if either, is favored by a given compound. In your post-lab assignment, you will be required to...
