BENZENE chemistry help

) The enthalpy of hydrogenation of cyclohexa-1,3-diene is not exactly double that of cyclohexene.
Suggest a value for the enthalpy of hydrogenation of cyclohexa-1,3-diene and justify your value.

I'm confused as to how I would find a value for the enthalpy of hydrogenation of cyclohexa-1,3-diene

Thanks for any help in advance!

You have to know that the value is between -239 and -121
A good estimate would be about -180
Reason: because there is only 1 single carbon bond separating 2 double bonds—> delocalisation occur
