What is the structure of benzene?

Benzene is an aromatic compound.

The structure of benzene is a 6 membered ring of carbons each bonded to eachother with a sigma bond, containing two electrons.

The remaining 6 electrons form a pi-cloud of electrons which are delocalised above and below the ring.

This means benzene is...

1. stronger than is expected

2. easily undergoes electrophilic substitution due to available electrons

3. unlikely to undergo addition reactions due to high stability
