About aromatic chemistry notes

GoConqr Original

Finding aromatic chemistry notes

The notes on this page range from introductions to benzene to accounts of its reactions. Start with Structure of benzene for its comparison of the Kekulé and delocalised models. Another note, Introducing Benzene, brings together an introduction and the models of its structure.

For a different starting point, the specification note sets out points to compare when studying those models. Benzene Recap offers a shorter route back into the topic.

Moving through the notes

Once you have reviewed structure, use Benzene Reactions alongside Electrophilic substitution of arenes. The latter explains why the stable benzene ring resists addition and introduces the general mechanism. Notes on chlorobenzene and phenol, and on activating and deactivating groups, provide further reading.

After reading, try recalling the key points without looking. When you want to check your recall in another format, visit the unit page and try a quiz.

Frequently asked questions

Which note is a useful place to start?

Start with Structure of benzene if you want to compare the Kekulé and delocalised models. Introducing Benzene is another option: it begins with an introduction to benzene before considering its structure. You can use either note before moving on to the reactions resources.

Which notes cover reactions and related compounds?

Benzene Reactions discusses substitution, while Electrophilic substitution of arenes introduces the general mechanism and the ring’s resistance to addition. The page also lists Chlorobenzene and Phenol, plus a note on activating and deactivating groups that discusses the reactivity of phenol.

Are these notes free to use?

Yes. Every resource listed here is free to open and study without an account. The notes were made by GoConqr users. You can browse the different titles and choose the explanations that are most useful for the part of Aromatic Chemistry you are reviewing.
