I have read about non-huckel double bonds and clar's rule, but what made me confuse is that huckel's perception gives me the feeling that central bonds in polycyclic aromatic hydrocarbons (ex: pyrene) is simply minimally affecting aromaticity or even dropped off, while clar's rule shows different resonance forms which in total makes a complete sextet formed in each ring of pyrene.
So how could i resolve this issue?
what would happen to aromaticity if simply the central double bond was not in the pyrene?
is there any cross-conjugation involved? and how would cross-conjugation affect aromaticity?
