    Benzene has a delocalised electron cloud of 6 electrons.


    it also has an odd enthalpy change when somethinged (I forget what), it's missing roughly -152 DeltaH

    now the only thing different between benzene and 1,3,5-cyclohexene (besides the enthalpy difference) is 6 delocalised electrons



    so the logical assumption is that 6 electrons equal DeltaH -152 enthalpy

    So am I right in thinking the energy of one electron is around -25?


    also with an electron being roughly 1/2000 of a proton, would a proton have an energy of around 50000?


    (please don't roast me on the numbers, I don't even know what enthalpy is measured in)

    benzene and 1,3,5-cyclohexene are the same chemical. Benzene is often drawn as cyclohexene, rather than with a ring. The electrons naturally delocalise because there is no charge/partial charge to cause them to become focused on a single point around the ring: each is equally likely to be in any place within the ring, so they can be seen as occupying all of it.

    Enthalpy change is, basically, the change in electric potential energy of the system in a reaction. It is measured in J/kJ.

    The energy in this case is not because of the electrons themselves, but rather because they move closer to a positive charge, and so lose potential energy.
