  Overview of Chapter Guide One

The goal of this assignment is to learn molecules "stick" together. This section includes topics such as Lewis structures, VSEPR, polarity, formal charges, and more.

Chapter 7 introduces us to a host of concepts which we will use repeatedly over the next two terms. Some of the material might be familiar to you; some may not be, but it is important to fully master the concepts before proceeding to subsequent chapters; in addition, this is a long chapter with many important concepts, so spend an adequate amount of time to ensure mastery. Especially important in Chapter 7 are the ideas of Lewis structures, VSEPR, formal charges, bond polarity, molecular polarity, bond enthalpy, and much more.

For a complete list of important concepts, see the Chapter 7 Study Guide.

  Resources for Chapter Guide One

To understand molecular bonding, you should read Chapter 7 in your textbook.

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

The Chapter Seven lecture notes which accompany this lesson will be helpful to you when going through this section. These are Web versions of the lecture notes I use in my "normal" CH 222 class and should let you see what is important to me in this chapter. You can also view the Lecture Notes in presentation software: Keynote, PowerPoint

Several handouts are available from Chapter Seven. Feel free to explore all of them

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

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 me to receive extra credit.

  1. Lewis Structures Informational Only
  2. Using Bond Enthalpies
  3. Born-Haber Cycles
  4. Dipole Moments

  Practice the Concepts of Chapter Guide One

Please complete problem set #1 to further explore molecular bonding. Problem set #1 covers several questions from Chapter 7 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 #1 (with answers included at the end) and/or the non-assigned problems in Chapter 7. 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.

Test your mastery of the subject matter by trying the self quiz for Chapter 7. This is an ungraded test that you can use to gauge your comfort level with these concepts. This sample Quiz #1 (answers) (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.
