Dashed line

what does the bond enthalpy mean when it has one dashed line and one solid line?

I believe this is for molecules like benzene to take into account resonance. In the molecular structure, some of the carbon-carbon bonds will be single bonds and others will be double bonds.

Yeah, it just indicates that it is the bond enthalpy for resonance bonds, so the value should be greater than a single bond but lower than a double bond.
