This unit provides a review of material covered in a standard general chemistry course through a discussion of the following topics:

the differences between organic and inorganic chemistry.
the shapes and significance of atomic orbitals.
electron configurations.
ionic and covalent bonding.
molecular orbital theory.
hybridization.
the structure and geometry of the compounds methane, ethane, ethylene and acetylene.

We recognize that students who are thoroughly familiar with a topic will not benefit from reviewing it; therefore, we have included a thirty-four item “entry level test” designed to allow you to assess your mastery of the material. If you answer all of the test questions correctly, proceed directly to Unit 2; if you correctly answer twenty-five or more questions, review the topics that posed problems and then go on to Unit 2; if you give correct answers to fewer than twenty-five of the thirty-four test items, you must work through the entire unit. Answers to the test questions are given at the end of Unit 1. You will note that the answer table also contains references to the sections of the textbook, Organic Chemistry, 8th ed., that discuss each topic.
