can visualize in a flat surface
2d
Planarity
alternating single and double bonds
equal energy all throughout
continuous conjugation
equal energy, equal distribution
resonance
overlapping of pi system = delocalized bonding = resonance effect = stable
continuous conjugation
4n + 2
Huckel's Rule
non negative integer including 0
n
lowest possible pi electron
2
arenes
aromatic compounds
compounds that consist of conjugated planar ring system accompanied by delocalized pi electron clouds in place of alternating double and single bonds
aromatic compounds
