Khan Academy: Aromatic Compounds: Directing Effects: Ortho Para Directors I

Sal gives a good recap of the pi electron behavior in aromatic compounds originating from a benzene ring. He diagrams the hybridization leading to a conjugated system of pi electrons and compares their stability.

Why can we smell aromatic and cyclic compounds and why they are in rings instead of lines? Viewers learn about organic compounds, resonance, naming standards for aromatic compounds, common chemical reactions, and the many uses...

A further exploration of the behavior of Ortho-Para Directors as moderator and weak activators, and weak deactivators. [9:37]

In this video lecture learn about aromaticity or aromatic stabilization. Video focuses on the aromatic molecule of benzene. Understand that aromatic compounds are classified by containing a ring and having a certain number of electrons...

An instructional video featuring the topic of regiochemistry. [12:58]

Jay explains how to name bicyclic compounds. Understand the numbering the chain and how to identifying bridgehead carbons. [10:29]

Did you know that 99 % of the aromatic compounds are either benzene or derived from benzene? This video will help you become familiar with the naming of the benzene molecules. [8:39]

This resource provides a summary of some fundamental math and science concepts that will be helpful in learning chemistry. Links are provided to help you learn or review the material on Khan Academy.

A video exploring the aromaticity of heterocycles which are rings containing one or more non-carbon atoms. [11:47]

Review the aromaticity of polycyclic compounds, such as naphthalene on this video. [9:26]
