  Overview of Chapter Guide Four

Chapter 10 introduces us to intermolecular forces, or the forces which keep molecules of the same compound together. Intramolecular forces (ionic, covalent and metallic) have been covered in previous chapters), while these intermolecular forces explain how two water molecules stay together. Typical IM forces include dipole-dipole, induced dipole - induced dipole (also known as London Dispersion forces), hydrogen bonding, ion-dipole, and several others. We shall rank the forces by strength to understand them and be able to assign the forces depending on the nature of the intramolecular bonds in the molecule.

We will also look at the intermolecular forces of solids, learning about simple cubic solids (simple cubic, body centered cubic and face centered cubic systems) and how to determine their radius and density using relatively simple transformations. We will also explore phase diagrams and understand how to use them. We will see once again how ordinary water is quite special with regards to other solvents, mainly due to hydrogen bonding.

For a complete list of important concepts in Chapter 10, see the Chapter 10 Study Guide.

  Resources for Chapter Guide Four

For this module, you should read Chapter 10 in your textbook.

The following screencasts and Complete Lectures might prove useful to you as you study this chapter.

The Chapter Ten lecture notes which accompany this lesson will be helpful when going through this section. These are Web versions of the lecture notes used in the "normal" CH 222 class and should let you see what is important in this chapter. You can also view the Lecture Notes in presentation software for Chapter 10 (Keynote, PowerPoint).

A variety of handouts are available from Chapter Ten. Feel free to explore all of them or just the ones which give you difficulty.

Once you have mastered the concepts listed above, check out the Chapter Ten Concept Guide for a series of worked problems relating to this module. They will help you to ensure the mastery of the knowledge from this section

Finally, test yourself (and get extra-credit in the bargain!) on the following chemistry concepts. If you get 9 out of 10 correct (or some multiple thereof), submit the information to receive extra credit.

  1. Intermolecular Forces
  2. Heat Transfer With Change in State
  3. Melting Ice
  4. The Clausius-Clapeyron Equation
  5. Calculations With Solids

  Practice the Concepts of Chapter Guide Four

Complete problem set #4 to further explore the ideas of solubility and entropy. Problem set #4 covers several questions from Chapter 10, and it can be found here. We will discuss problems like these during recitation, so come prepared to ask and answer questions.

For additional practice, try completing practice problem set #4 (with answers included at the end) and/or the non-assigned problems in Chapter 9 and Chapter 10. Answers to many of those problems are listed in the back of your textbook.

If you need assistance on these problems, you have several options. You can visit the AVID / Learning Success Center located above the MHCC library on the Mt. Hood Community College campus; they have tutors available to help you with your chemistry homework. You can also contact me if you have any questions.

This sample Quiz #4 (with answers at the end) which was given during a previous year's CH 222 class will help you understand the kind of questions that will be asked on the quiz.

You can also test your mastery of the subject matter by trying the self quiz for Chapter 10. This is an ungraded quiz that you can use to gauge your comfort level with these concepts.
