"Intermolecular forces are the forces between molecules, whereas intramolecular forces are those within molecules. (The bonds that hold the atoms in a molecule together are intramolecular forces.) A quick note before we jump in: When chemical educators are explaining intermolecular forces, they almost always use examples of intermolecular attractions..."

As promised at the end of my post on polar and non-polar molecules, here's a basic concepts post on intermolecular forces. Intermolecular forces are the forces between molecules, whereas intramolecular forces are those within molecules. (The bonds that hold the atoms in a molecule together are…
Some months ago I made a (seemingly idle) threat to follow up my basic concepts posts on polar and non-polar molecules and intermolecular forces with a post on phase changes. Finally it's here!
Since the discussion here will be leaning on a number of the concepts discusses in the earlier posts,…
What list of basic concepts would be complete without a primer on polar and non-polar molecules?
You'll recall that chemists live in a world made up of atoms and various assemblies and modifications thereof, which are, in turn, made up of protons, neutrons, and electrons. Protons (which have…
My last post for the basic concepts series involved phases of matter and transformations from one phase to another. This post will look at how a phase change can be put to practical use in a common household appliance -- the freezer. My aim here is to give you a good thermodynamic feel for how a…
