Term. 4 rules of aromaticity: PAH: polycyclic aromatic hydrocarbon, 2 fused aromatic rings with a planar structure. Example: Chrysene. A Ring is aromatic if it has (4n + 2) pi electrons where n= 0,1,2,3,4..... Breaks one or more rules of aromaticity (stated previously) Examples: 1-hexyne, 1-heptyne, 1-octyne. 1.
23 Φεβ 2017 · 1. Four Key Rules For Aromaticity. There turn out to be 4 conditions a molecule must meet in order for it to be aromatic. It’s all or nothing. If any of these conditions are violated, no aromaticity is possible. First, it must be cyclic. Second, every atom in the ring must be conjugated.

In this case, conferring Hückel 4n+2 aromaticity. For furan with two lone pairs on the oxygen atom, if we count electrons from the carbon atoms, we have 4 (one per carbon). So adding two electrons from one of the lone pairs will give 6 = 4(1)+2, so Hückel rule is applicable and furan is aromatic.
