I think , when we add surfactant in a solution , surface tension of that solution become low. boiling point of any solution just depend on force of attraction between molecules as much as attraction is high boiling point is high. as we know surface tension of solution became low means force of attraction between the molecules will be low , so in this way boiling point of that solution will become low......
Hydrogen bonding affects the boiling point of water by increasing the temperature at which water will boil.
Because of its hydrogen bonding.
Ethanol has intermolecular hydrogen bonding where as diethylether does not have this kind of bonding. So BP of ethanol is higher than diethylether.
CH3NH2 has the higher boiling point as it has a hydrogen bond between the molecule which is a stronger intermolecular attractive force, whereas CH3CH3 only has covalent bonds which are weaker intermolecular attractive forces.
NH3 exhibits hydrogen bonding in addition to dispersion forces. This significantly increases the intermolecular force, and raises the boiling point. PH3 does not exhibit hydrogen bonding and the dominant intermolecular force holding these molecules together is dispersion forces. (Dispersion forces also known as Van Der Waal Force)
Simple hydrocarbons, like methane and ethane. As the carbon chain gets longer, the boiling point goes up. -------------- Some elements, such as helium, hydrogen, nitrogen and neon have extremely low boiling points. Please see the link.

Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.
Hydrogen bonding
hydrogen bonding increases the intermolecular attractions and therefore increases the boiling point and melting point.
Because of strong hydrogen bonding.
It is due to the strong hydrogen bonding in the hydroxyl groups of the ethanol. Since the molecules of ethanol are held together more strongly than acetone, it requires more energy to change ethanol into a gas.
