Benzene

?

Structure of Bezene

flat triganol planar

mechanism: heterolytic electrophilic subsitution

- Benzene is unsaturated

- Benzene is more thermodynamically stable because of its ability to have a continous system of delocalised electrons.

- lower reactivity => higher thermodynamical stability

Evidence for benzene's delocalised structure

1) Benzene does not react with Br2 therefore no double bond

2) All bond lengths in benzene are equal => bond order 1.5

3) Enthalpy of hydrogenation of Benzene is low => more thermodynamically…
