Aromaticity is one of the more exciting topics in organic chemistry!
Partly because of it's potential for easy points on your quiz/exam.. that is IF you truly understand, not merely memorize: when you know what to look for to identify aromatic, antiaromatic and non aromatic compounds.
Start with the Aromaticity Review + Videos, then see how much you’ve mastered with the Aromaticity Practice Questions below.

Hint: Review the last video in the Aromaticity Tutorial series
Part 3: Acidity and Basicity of Aromatic Compounds
Choose the most acidic/basic molecule or ion in each pair as specified below
Hint: When CARIO looks the same, compare the stability of the conjugates
Bonus Aromaticity Questions

I would like to test myself to see if I truly understand Aromaticity, however I don’t know when the solution PDF will come out and I currently can’t join the Study Hall.
