EAS Mechanism and Sigma Complex Resonance Video

EAS reaction mechanism and sigma complex resonance structures

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 […]

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

electrophilic aromatic substitution introduction tutorial

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 […]
