Aromatic hydrocarbons

Introduction
Benzine
Seems to be part of the unsaturated hydrocarbons (double bonds) but they have so different properties that they form their own group.
Often have strong smell which has given them their names. Their nomenclature is based on a number of base structures: benzene, naphthalene, anthracene etc.

- Benzene as a substituent = phenyl.
- The benzene ring consists of 6 carbon atoms and three double bonds.
- The double bonds are not locked in position so all six bonds in the ring are.
- Identical (this is called aromaticity – not only for carbon).
- This yields a stable molecule.
