Okay, i understand the structure of benzene, but the specification says that we should be able to justify the structure using bond enthalpies and different types of double bonds. Could anybody explain this?

the enthalpy change for the electrophicic addition of hydrogen to cyclohex-1,3,5-triene is more exothermic than the enthalpy change from the same addition of hydrogen to benzene, indicating benzene is of a different and more stable structure.
Also nthe bond lengths measures in the Kekulé structure should be alternating larger and smaller as a double bond is shorter, but in benzene the bonds between carbons were all the same length.

check out this page
shows the enthalpy issue and the bond length
