Old CH 231 Exams The questions on these old exams are typical of the kinds of questions you can expect on the exams in CH 231 this semester. For the midterm exam, you should know all of the material in chapters 1-5, with one exception: you will not be tested on Fischer projections (section 5-4). The absence of questions about any particular topics on the old exams does not imply that questions on those topics will also be absent on the midterm exam this fall. The overall degree of difficulty of the midterm exam this fall will be comparable to that on the old exams, although there will undoubtedly be some variations in the degree of difficulty of individual questions on specific topics. You should be able to answer all of the questions on old exam 1 and all of the questions except 9, 12, 13, and the bonus on old exam 2. L. T. Scott 10/12/2004
