Lesson summary: Water and life (article) | Khan Academy
Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is 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 …
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 …
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 …
Cohesion and adhesion of water (article) | Khan Academy
Learn about cohesion, adhesion, and surface tension of water and how they relate to hydrogen bonding.
Water as a solvent (video) | Khan Academy
Water, due to its polarity, acts as a fantastic solvent, especially for polar substances and ions. This is because the positive and negative ends of water molecules are attracted to ions, …
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 …
Molecular polarity (video) | VSEPR | Khan Academy
Let's go ahead and analyze a water molecule over here on the right. So the electrons in this covalent bond between the hydrogen and oxygen, oxygen is more electronegative than …
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 …
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 …
