Aromaticity Practice Problems for Aromatic, Antiaromatic, Nonaromatic

February 21, 2019 By Leah4sci 5 Comments

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.

Scroll down for PDF Solutions

Part 1: Aromatic, Antiaromatic, Non Aromatic

Determine if each molecule below is Aromatic, Antiaromatic or Non Aromatic. Explain your reasoning.
Need help? Review the first 2 videos in the Aromaticity Tutorial series

Part 2: Aromatic Electrons

Which lone pairs (if any) in each molecule are aromatic and part of the resonating system?
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

    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.
