Resonance Structures of Benzene

Benzene Resonance step by step in Video Tutorial Series by leah4sci

Benzene is a unique molecule when it comes to resonance structures. This video will show you how to draw the ‘circle’ of resonance for benzene, as well as resonance intermediates for substituted aromatic compounds including Electron Donating Groups EDG which resonate into the ring and Electron Withdrawing Groups EWG which cause resonance out of the ring. […]

Aromaticity Tutorial for Cyclic, Charged and Heterocyclic Aromatic Compounds

Heterocyclic aromatic molecules aromaticity tutorial pyrrole pyridine thiophene

Aromaticity is one of the more exciting topics in organic chemistry, typically covered right before Electrophilic Aromatic Substitution. The concept can be tricky but the rules are relatively straightforward. Once you master this topic, aromatic questions become the source of quick and easy points, on an otherwise more difficult exam. In this tutorial I will […]
