1. The problem statement, all variables and given/known data Which one of these had the highest boiling point? A. 3-Pentanone B. 1-Butanol C. Butanal 2. Relevant equations 3. The attempt at a solution The answer should be 3-pentanone because 1- it's molecular weight is approx 76 compared to the other which has approx 64 2 - because of the dipole-dipole attraction. However when I googled the boiling points for each one it says that Butanol has the highest. Why is it that?
