Ethanol molecules have the ability to form Hydrogen bonds with each other ( H from one molecule with O of another).
Propane cannot form hydrogen bonds.
Thus one needs more energy to break these bonds in order to evaporate.
Hydrogen Bonding in ethanol but not in propane
Ethanol has hydrogen bond where as ether does not.

Octane has a higher boiling point than pentane because octane has a larger number of carbon atoms than propane
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.

ethanol has a higher boiling point- of 78°C :)
Oxygen.
I think propane is higher??

It depends what chemical or compound you are comparing the boiling point to. Ethanol has an atmospheric pressure boiling point of 78.1 °C (172.6 °F). This is slightly lower than the boiling point of water at the same pressure, much lower than the boiling point of iron, much higher than the boiling point of bromine.
Octane has a higher boiling point than pentane because octane has a larger number of carbon atoms than propane
78.3 degrees Celsius is the boiling point of ethanol.

The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
i think it's because there are strong covalent bonds needed to be broken.
