Aromatic Sulfonation Reaction and Mechanism Tutorial Video

aromatic sulfonation reaction mechanism EAS by leah fisch

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

Aromatic nitration mechanism for electrophilic aromatic substitution

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 […]

EAS Aromatic Halogenation Reaction and Mechanism Tutorial Video

Aromatic Halogenation Electrophilic Aromatic Substitution

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 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 […]
