Introduction to Rearrangement Reactions
Introduction to Rearrangement Reactions Reactions that involve a carbocation intermediate may be accompanied by rearrangements where a pair of electrons from a C-H or C-C bond

Are these molecules conjugated?
If Org 2 has an overall theme, it’s “resonance”. Today’s post has a very simple message. Atoms with lone pairs, π bonds, radicals, and carbocations can
