Describe the structure and bonding of benzene.

Benzene consists of a ring of 6 carbon molecules. Each of these carbon molecules are bonded to each other by single bonds. This leaves free electrons in p-orbitals. The p-orbitals overlap, creating pi-bonds and a region of electron density both above and below the carbon ring. The electrons in this region are able to move freely, and hence there is no one clear region with a higher electron density.
