Polarity Resonance and Electron Pushing - Crash Course Organic Chemistry
We’ve all heard the phrase “opposites attract.” It may or may not be true for people, but it’s definitely true in organic chemistry. In this episode of Crash Course Organic Chemistry, we’re learning about electronegativity, polarity,...

Balloon and Treacle
We investigate the effect that unbalanced charge has on polar molecules. We rub a balloon against hair to build up a negative charge and then hold this near a stream of water and then a stream of treacle. They both bend towards the...
Professor Dave Explains
Performing Column Chromatography
We just learned about thin layer chromatography, but a much more industrially relevant technique is column chromatography. This is how we will separate large quantities of compounds in a mixture by virtue of their differing polarities....

How Polarity Makes Water Behave Strangely
Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...

Recognizing Polar Molecules
Bend — yes, bend — water by taking advantage of its polar property. The instructor featured in this video examine bonds to determine if a molecule is polar or nonpolar and explains situations that would create a polar compound.

Khan Academy: Solubility of Organic Compounds
Organic compounds tend to dissolve well in solvents that have similar properties to themselves. This principle is often referred to as like dissolves like, which means that polar molecules will generally dissolve well in polar solvents...
