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.

Aromaticity Practice Quiz: See how well you know aromatic, antiaromatic and non aromatic compounds along with aromaticity tutorial videos to fill in the gaps.
This section will try to clarify the theory of aromaticity and why aromaticity gives unique qualities that make these conjugated alkenes inert to compounds such as Br 2 and even hydrochloric acid. It will also go into detail about the unusually large resonance energy due to the six conjugated carbons of benzene.
