Describe the Structure of Benzene and its differences to Cyclohexetri-1,2,3-ene

Benzene has a molecular formula of C6H6. It has a ring of pi electrons that work above and below the plane of structure, formed by overlapping of p-orbitals. This means it has a more stable structure, only a delta H of -208 kJ per mole as opposed to -360 kJ per mole for the enthalpy hydrogenation of the ring due to the stability. This makes it more stable as the pi electrons are more spread out and they are not localised within the structure itself. Benzene will also be less reactive than cyclohextriene due to this, requiring a halogen carrier to react with chlorine, e.g. AlCl3 rather than just heat. Each carbon in its structure has 2 sigma bonds to other carbons, one sigma bond to a hydrogen and one electorn which is held in the p-orbital. It also has bonds lengths which are the same of 0.139 nm, which is shorter than a single bond of 0.153nm for Carbon to Carbon (C-C) and longer than double bonds between Carbon atoms at 0.134 nm.
