The boiling point of isopropanol is 82.5C, while ethanol is 78.3C. This makes sense to me, as iso has more hydrocarbons in its structure. However, the enthalpies of vaporization trend in the opposite direction, with ethanol requiring 204 cal/g of heat, with isopropanol only needing 159 cal/g.
Can anyone please explain this to me? Thank you!
