Resonance Trick Ortho Meta Para Addition EAS Intermediates
EAS Series: Video 10 Electrophilic Aromatic Substitution gets more difficult when the starting molecule is a substituted benzene. Not only do you have to know the reaction. You also have to know how the substituent will direct the incoming electrophile, and if the substituent will slow down (deactivate) or speed up (activate) the overall reaction. […]
Ortho Meta and Para Disubstituted Benzene Monster Trick Video
EAS Series: Video 9 This video shows my fun trick for easily recognizing ortho, meta, and para substituents on a disubstituted benzene. This will be extremely important once you start reacting substituted benzene. (Watch on YouTube: Trick.

Friedel Crafts Alkylation EAS Reaction and Mechanism Video
EAS Series: Video 6 This video shows you the mechanism for the formation of carbocation in a Lewis Acid as the super electrophile that is attacked by benzene in the Friedel-Crafts Alkylation reaction. This reaction produces an alkylated benzene. (Watch on YouTube: Alkylation. Click CC on bottom right for transcript.) <– Watch Previous Video: EAS […]
Aromatic Sulfonation Reaction and Mechanism Tutorial Video
EAS Series: Video 5 Aromatic Sulfonation is an Electrophilic Aromatic Substitution (EAS) reaction which adds an SO3H to the benzene ring. This reaction can be carried out starting with SO3, or creating SO3 using a heated H2SO4 solution. The video below shows the complete mechanism from creating a super electrophile (SO3) to sigma complex and reforming the benzene […]
EAS Aromatic Nitration Reaction and Mechanism Video
EAS Series: Video 4 This video shows you the mechanism for the formation of Nitronium – the super electrophile that is attacked by benzene in the nitration reaction. This video also helps you understand the role of the acid catalyst before and during the reaction. (Watch on YouTube: Nitration. Click CC on bottom right […]
