Using the tables of enthalpies of formation and entropies of formation, estimate the boiling point for the following liquid: methanol (CH3OH), ethanol (C2H5OH) and acetic acid (CH3COOH). compare to their tabled boiling points.

how would i go about working this question?

table values:
mbp methanol- 65.15 degrees C
mbp ethanol - 78.5 degrees C
mbp acetic acid- 117.9 degrees C
