What are the Key features of benzene?

A Level

The electrons/ Pi bonds are delocalised2. It is made up of six Carbons in a ring with two rings of electon density above and below the plane of the ring.3. It has a lower electron density than alkenes with a similar structure (aka hexene) and phenol because of the delocalised system.4. It does not induce a dipole/ polarise many molecules because of it's lower electron density making it relatively inert.
