Although benzene is normally written with three double bonds, benzene is not reactive towards many reagents that alkenes normally react with. This lack of reactivity can be explained by the unusual stability created by cyclic conjugation.
(i) describe at least one of the physical properties of benzene that demonstrates how the true structure of benzene does match the way the structure is normally written
(ii) explain how the unusual stability of benzenecan demonstrated by its thermodynamic properties through some form of experiment.
(iii) include an appropriately labeled diagram as part of your answer (you do not have to quote any numerical values)
