Electrophilic Aromatic Substitution Study Guide Cheat Sheet

February 6, 2020 By Leah4sci

EAS Cheat Sheet Preview

Electrophilic Aromatic Substitution reactions are one of the more fun topics that you will study in Organic Chemistry. But perhaps you find it tricky due to the sheer volume of information that makes up the big picture. And so, in addition to my EAS Tutorial Video Series I’ve put together a thorough EAS cheat sheet. […]

EAS resonance for ortho meta and para substituents

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. […]

Aromatic Sulfonation Reaction and Mechanism Tutorial Video

December 29, 2015 By Leah4sci

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 […]
