Identify the number of steps (patterns) for the mechanisms in Problems. For example, the patterns for the first two are:

a: ±H^± €“ LG €“ Nuc attack This mechanism exhibits a proton transfer before the two core steps.

b: ±H^± €“ LG €“ C^± rearrangement €“ Nuc attack This mechanism exhibits a proton transfer before the two core steps as well as a carbocation rearrangement in between the two core steps.

These patterns are not identical. Draw patterns for the other six problems. Then compare the patterns. There is only one pattern that is repeated in Problem. Identify the two problems that exhibit the same pattern, and then describe in words why those two reactions are so similar.
