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.

Phenols 1

This video outlines the basic information for phenols such as, naming, properties and their reaction with alkalis and metals.
