Overview: Aromatic Compounds
This is an overview of Topic 29: Aromatic Compounds. It includes bonding and structure of benzene, reactions, electrophilic substitution mechanism, phenol, directing groups and relative reactivity.
Structure and Bonding in Benzene
Video introducing benzene including the structure and bonding of the Kekulé model and delocalised model for benzene.
Evidence for Benzene’s Structure and Bonding
This video provides the evidence which led to the Kekulé model being rejected and the delocalised model of benzene being accepted.
Reactions of Benzene
This video looks at the mechanisms of nitration and halogenation of benzene.
This video looks at both mechanisms for Friedel-Crafts alkylation and acylation and has a worked exam style question.
Comparing the Reactivities of Benzene and Alkenes
This video gives an explanation as to why alkenes are more reactive than benzene using bromination as an example.
This video outlines the basic information for phenols such as, naming, properties and their reaction with alkalis and metals.
Video explaining the reaction of phenol and bromine and why phenols are more reactive than benzene. The video also gives some uses of phenol.
Aromatic Directing Groups
Video explaining the effect of directing groups OH, NH2 and NO2 groups on substitution reactions of benzene rings.
