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 […]
Naming Aromatic Compounds
Naming Organic Compounds Series: Video 20 This video and the following video will take you through the steps for naming aromatic compounds using their common names, as substituents off larger molecules, and as a parent molecule using ortho / meta / para. Click HERE for the Naming Aromatic Compounds Cheat Sheet (Watch on YouTube: Aromatics 1. […]
Naming Aromatic Compounds Part 2 Ortho Meta Para Substituents on Benzene
In the previous video, Part 1 of the Aromatic Nomenclature, you saw how to name Benzene molecules using IUPAC and common nomenclature for a substituted benzene. This tutorial video below, Part 2, will walk you through the IUPAC rules for naming disubstituted benzene compounds using ortho meta and para. (Watch on YouTube: Aromatics 2. Click […]
Halogen Exception Ortho Para Deactivators Tutorial Video
EAS Series: Video 13 This video shows you the unique directing effects of halogens on substituted benzene. Learn why they are ortho para directing yet still deactivate the benzene ring towards electrophilic aromatic substitution. (Watch on YouTube: Halogen Exception.

Resonance Structures of Benzene
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.
