Bond Enthalpies

If you're looking at a carbon ring, which bond enthalpy would you use considering that there is a mix of double and single bonds between the carbons

You would look at the total of all of the bonds: the three C=C bonds and three C-C bonds, for instance.

This is definitely one way to find enthalpy. Also keep in mind that in real life, any molecules with multiple types of bonds result in resonance hybrids. Thus, if the bond enthalpy of a resonant bond is given, you can just use 6 of those.
