Because isopropanol, as an alcohol, has hydrogen bonding between its alcohol hydrogens and oxygens, increasing intermolecular forces and thus increasing boiling point.
Acetone, a ketone, has very little hydrogen bonding because its hydrogens don't have electron density taken away from them since they're not attached to oxygen (in other words, they're not acidic).

Why acetone have more cooling effect than water?
Acetone has a lower boiling pt. than water because it has a higher vapor pressure. Liquids boil at the temperature where their vapor pressure is equal to the atmoshperic pressure. The temperature that acetone must get to, such that its v.p. is equal to the pressure of the atmosphere, is lower than what is required for water. Therefore, acetone has a lower B.P.
Why does beer boil at a lower temperature than tap water?
Beer boil at a higher temperature than tap water because contain many solutes.
How can a substance boil to a higher temperature with the same rate of heat provided?
A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.
Will rainwater and sea water boil at the same temperature?
No, rainwater and seawater will not boil at the same temperature. Seawater has a higher boiling point than rainwater due to the presence of dissolved salts and minerals, which raise the boiling point of the water.
When salt is added to boiling water at 100 degrees Celsius will the water boil faster or slower?
Adding salt to boiling water will actually make the water boil slower. Salt increases the boiling point of water by raising its boiling point temperature. As a result, it will take longer for the water to reach the new, higher boiling point temperature and thus boil.
Do molecular compounds boil at a higher temperature than ionic compounds?
No

Why does water boil at a higher temperature in a pressure cooker?
less than 100oC.

Does petrol boil at a higher temperature than diesel?
No. I'm not sure of the exact numbers. Petrol will boil off of your hand, while Diesel will not. Try it if you get the chance.

Predict whether water would boil on top of a mountain at a higher or lower temperature than at sea level?
Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.
Why would water take longer to boil at elevations above sea level?
Water takes longer to boil at higher elevations because the atmospheric pressure is lower, which reduces the boiling point of the water. At higher elevations, there is less air pressing down on the water, so it needs to reach a higher temperature to boil.
Does water boil faster if it contains salt?
Salty water boils at a higher temperature than pure water does.
Does argon boil at a higher temperature than helium?
Yes, argon boils at a higher temperature than helium. Argon boils at -185.86°C whereas helium boils at -268.9°C.
