EAS Aromatic Halogenation Reaction and Mechanism Tutorial Video

EAS Series: Video 3 This video will start by showing you a quick comparison of alkene halogenation versus aromatic halogenation: bromination and chlorination. This video will show you the aromatic halogenation mechanism from the role of the Lewis Acid catalyst and formation of the super-electrophile, through the entire mechanism of adding halogen to benzene. Also […]

EAS Mechanism and Sigma Complex Resonance Video

EAS Series: Video 2 The Electrophilic Aromatic Substitution reaction starts when one of the pi electrons on the benzene rings breaks as it reaches for the super electrophile. While this is similar to alkene reactions AT FIRST GLANCE the remainder of this mechanism is very different and unique. The sigma complex intermediate is capable of […]

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. […]

Introduction To Electrophilic Aromatic Substitution

EAS Series: Video 1 The topic of EAS or Electrophilic Aromatic Substitution reactions is one that covers a key reaction pathways studied in the average organic chemistry course. While the mechanism undergoes a broken pi bond and addition to the former sp2 carbon atom, the EAS reaction is very very different from the Alkene Addition […]
