Aromaticity Rules + Cyclic, Charged and Heterocyclic Aromatic Compounds

February 18, 2016 By Leah4sci

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 […]
