The compound is bigger. They all contain -OH branches but propanol has 3 carbons, whereas ethanol has 2 carbons, and methanol has 1 carbon. There are more intermolecular forces which increases boiling points.
Liquid propanone (common name acetone) has a boiling point in the absence of propanone vapor in the surrounding atmosphere of
56-57 °C, = 329-330 °K = 133-134 °F
being the slight variability due to pressure conditions.
Propanol has a higher boiling point because it contains an OH (hydroxyl group). The hydroxyl group indicates there is hydrogen bonding. Hydrogen bonding is stronger than dipole-dipole bonding and London forces -which is the intermolecular bonding in propanone.
Although in both alcohols the inter-molecular forces in play are hydrogen bonds, propan-1-ol is a straight chain alcohol where as propanan-2-ol is branched. This fact weakens the intermolecular forces by decreasing the distance of closest approach of the molecules
Because propane has more intermolecular forces (i.e. London Dispersion et al) and thus stronger bonds. Remembering that heat is energy, it makes sense that you must add more energy (more heat) to break a strong bond compared to a weak bond.
1-propanol = 82oC [Boiling point]
propanone = 56oC [Boiling point]
so...1-propanol has a higher boiling point.
1-propanol = 82oC [Boiling point]
methanol= 64.7oC [Boiling point]
Pentanone
Chlorine has higher boiling point.
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Sea water has higher boiling point,as it contains sodium chloride
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.

The boiling point is higher.
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
The boiling point is always higher than the melting point.
iodine is having higher boiling point
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Higher then the boiling point of the solvent.
Sea water has higher boiling point,as it contains sodium chloride
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.
Sodium chloride has a higher boiling point.
