The table above shows the structural formulas and molar masses for three different compounds. Which of the following is a list of the compounds in order of increasing boiling points?

The boiling point is related to the strength of intermolecular forces.

Since the molar masses are similar, the london dispersion forces will be similar in all three compounds.

Due to the electronegative oxygen, acetone and 1-propanol have diplole-dipole forces.

1-propanol can also form hydrogen bonds since there is a hydrogen atom attached to the electronegative atom. Hydrogen bonding is typically stronger than dipole-dipole interactions.
