What effect does the structure of the alkyl halide (the substrate) have on SN1 and SN2 reactivity? For each reaction mechanism (SN1 and SN2) compare simple primary, secondary, and tertiary alkyl halides. Compare unhindered primary and hindered primary alkyl halides. Compare unhindered primary and allylic primary alkyl halides (Three different primary alkyl halides were examined). Make sure that you rationalize their relative SN1 and SN2 reactivities
