Hydrogen bonds in water (article) | Khan Academy
Water owes these unique properties to the polarity of its molecules and, specifically, to their ability to form hydrogen bonds with each other and with other molecules. Below, we'll look at how …
Solubility and intermolecular forces (video) | Khan Academy
Now, what do you think is going to happen if I try to put, say, some hexane, if I view that as a solute, and I were to put it in water? Well, in that situation, the water is going to be far more …
Solvent properties of water (article) | Khan Academy
Water interacts differently with charged and polar substances than with nonpolar substances because of the polarity of its own molecules. Water molecules are polar, with partial positive …
Cell membrane introduction (video) | Khan Academy
For example, water is polar because oxygen likes to "hog" electrons, giving the oxygen head a partially negative charge. The hydrogens, then, get a partially positive charge, since the …
Cohesion and adhesion of water (article) | Khan Academy
Learn about cohesion, adhesion, and surface tension of water and how they relate to hydrogen bonding.
Molecular polarity (video) | Khan Academy
Polar molecules, like water, have partial charges and form strong interactions such as hydrogen bonds, while non-polar molecules, like oil, have no significant charges and interact through …

States of matter | High school chemistry | Science | Khan Academy
Activity: How does water form droplets on surfaces? In this hands-on activity, students will investigate how different intermolecular forces of attraction impact the physical properties of …
