Polarity and intermolecular forces

Why do compounds act the way they do?  Why do chemical reagents fit together in just the right way for reactions to occur?  These are important questions, and these tutorials should help you to understand them.

Note:  If you’re not very good at Lewis structures, hit the “back” button and find the tutorials on how to do them.  You can’t explore polarity or IM forces without it. (Updated 6-7-22)

  • All about polarity:  What makes a molecule polar, and what effect does this have on the molecule’s behavior.  If you want to understand chemistry, you really need to learn this stuff.
  • Intermolecular forces:  Think of this as the second part of the polarity tutorial, because it explains the specific ways in which polarity causes compounds to interact with each other.
  • Polar covalent bonds and compounds:  Where is the polarity of a chemical compound derived from bond polarity?  What does that last sentence even mean?  You’ll find out in this PowerPoint.
  • Polarity II:  What does it mean for the properties of a compound when it’s polar?  Find out in the second PowerPoint of the series (the first one is directly above this one).
  • States of matter, phase changes, and IM forces:  This covers it all!  From a textbook I never finished.
