The enthalpies of reaction of the five n-heptenes with trifluoroacetic acid in the presence of a strong acid catalyst have been measured. A combination of these data with the available combustion data for the alkenes allows the enthalpies of formation to be determined with higher precision than previously possible. The differences in enthalpies of formation of the n- pentenes also were determined. The enthalpies of reaction of the three n-heptyl alcohols ...
