WitrynaA.Hydrogen bonds involve hydrogen bonded to carbon, nitrogen, oxygen, or fluorine. B.In a hydrogen bond, the hydrogen atom on one molecule is attracted to unpaired electrons associated with nitrogen, oxygen, or fluorine on another molecule. C.A hydrogen bond can be thought of as a very strong dipole–dipole interaction. WitrynaSurface tension - resistance to distortion at the surface of the liquid from poking; The core principle is that the stronger the IMFs in the sample of molecules, the more strongly they interact, which means they stick together more. That leads to the following trends: Stronger IMF #-># Higher melting and boiling points (harder to melt and boil) northgate dereham high school term dates

WitrynaAs temperature increases, VP increases. Stronger IMF mean that it requires more energy to overcome the IMF and enter the gas phase. Thus, the rate of evaporation will be lower and the VP will be lower. ... Surface Tension. Surface tension is a property of liquids that arises due to the fact that the molecules at the surface of a liquid have a ... WitrynaSurface tension: Liquids with stronger intermolecular forces tend to have higher surface tension than those with weak intermolecular forces. For example, if you pour a very small amount of water on a table, it will tend to collect together in one large drop. On the other hand, if you do the same thing with lighter fluid, which has weaker ...

Witryna23 lut 2016 · Since hydrogen bonds are the strongest intermolecular force, the molecules of water are going to have higher surface tension than the molecules of the mineral oil. Mineral oil is non-polar, therefore the only interaction it can achieve would be a London Dispersion Force, resulting in super low surface tension.
