  Overview of Chapter Guide Six

This module has two portions. The first portion (Chapter 19) examines briefly the fascinating chemistry of the transition metals and coordination compounds. The second portion (Chapter 21) examines very briefly the nomenclature of organic chemistry compounds.

Chapter 19 is an introduction to inorganic chemistry, especially the chemistry of the transition metals. The chapter extends the work of previous chapters to encompass the bigger metals with d-orbitals which leads to coordination compounds, and we learn about the behavior associated with these inorganic compounds.

For a complete list of important concepts in Chapter 19, see the Chapter 19 Study Guide.

Carbon is critical for life. Proteins, DNA, sugars, fats - all of these have carbon. The reason carbon is included is due to its flexibility (it can exist in a variety of geometries) and its relatively quick reactivity (reactions occur readily, something critical for life processes). To understand the magnitude of carbon, we will study several of the chemical families which include carbon. In addition, we shall explore some of the typical reactions that carbon undergoes while in some of the families. Polymers will also be explored.

Chapter 21 introduces us to the concept of chemical families which have a characteristic functional group in common. Some of the classes of families we will become familiar with include alkanes, alkenes, alkynes, aromatic compounds, ketones, aldehydes, alcohols, carboxylic acids, amines, amides, and many more. We shall also explore several typical organic reactions which utilize some of these families. Finally, we shall briefly explore the world of polymers, one of the most important of the chemical industries.

For a complete list of important concepts in Chapter 21, see the Chapter 21 Study Guide.

  Resources for Chapter Guide Six

For this module, you should read Chapter 19 and Chapter 21 in your textbook.

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

The Chapter Nineteen lecture notes and Chapter Twenty-one 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 223 class and should let you see what is important in this chapter. You can also view the Lecture Notes in presentation software: Chapter 19 (Keynote, PowerPoint) and Chapter 21 (Keynote, PowerPoint).

A variety of handouts are available from Chapter Nineteen and Chapter Twenty-one. 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 Nineteen Concept Guide and the Chapter Twenty-one 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. Crystal Field Treatment of Octahedral Compounds
  2. Recognizing Organic Fragments
  3. Basic Organic Nomenclature

  Practice the Concepts of Chapter Guide Six

Complete problem set #6 to further explore the main group metal and transition metal concepts. Problem set #6 covers several questions from Chapter 19 and Chapter 21, 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 #6 (with answers included at the end) and/or the non-assigned problems in Chapter 19 and Chapter 21. 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 #6 (with answers at the end) which was given during a previous year's CH 223 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 19 and the self quiz for Chapter 21. These are ungraded quizzes that you can use to gauge your comfort level with these concepts.
