Question

Conditions under which rearragement reactions occur

Answer 1

The 1,2-rearrangement takes place under acidic conditions. The name of the rearrangement reaction comes from the rearrangement of pinacol to pinacolone.

Answer 2

Rearrangements occur to create more stable carbocations. Reviewing carbocation stability from chapter 5 is helpful in identifying carbocations that can undergo rearrangement. Once rearranged, the molecules can also undergo further unimolecular substitution (S N1) or unimolecular elimination (E1)
