- Overlap of p-orbitals- π bonds.
- Delocalised π system.

Evidence against the Kekule structure
- All the C-C bonds are the same length.
- Benzene doesnt readily undergo addition reactions (e.g. it doesn't decolourise bromine water).
- The enthalpy of hydrogenation of benzene is lower than would be expected from the Kekule structure. This is because it is thermodynamically more stable due to the delocalised electrons.

- Aromatic alcohol.
- An OH group is attached directly to a benzene ring.
- Almost colourless crystalline solid.
- It is synthesised via a multi-stage process.

Reactions of phenol
- It is a weak acid so it partially dissociates in water.
- It can react with sodium hydroxide to form a salt.
- It doesn't react with carbonates as it is not a strong enough acid.
