Organic Chem Notes 10/26/1711/2/17 Carbocation stability trend o Tertiary and secondary allylic/benzylic > secondary and primary allylic/benzylic > primary > methyl Carbocation rearrangement o A carbocation always tries to be tertiary o HEAR ALARMS when you see a secondary carbocation (might be able to rearrange) o Rules: Can perform a methyl (CH3) shift or hydride (H+) shift Can only move these things from neighboring carbons CANNOT do multiple rearrangements Leaving Group: stable anions o Cl Br I o F is not a good LG because it is highly reactive (very unstable) o Strong bases are
