เนื้อหาย่อ : Two general approaches often used in teaching the one-year introductory organic laboratory are the investigative approach, a tutorial method that prepares the student for research, and what we call the "techniques approach,"' a more structured method in which the student is generally first taught manipulative techniques, then synthesis, and finally organic qualitative analysis. We have chosen the techniques approach because we feel it is more efficient of time and energy (both the student's and the instructor's) in our own chemistry sequence, in which students take lecture and laboratory courses concurrently. Techniques and Experiments for Organic Chemistry begins with the common laboratory techniques. Actual syntheses are postponed until the student has gained sufficient knowledge of organic chemistry from the lecture portion of the course understand the experiments being performed. Synthetic work follows the echnique chapters of the text and begins with alkyl halide chemistry (Williamson ether synthesis and a Grignard reaction), followed by alcohol chemistry. Spectral chniques (infrared and nmr) are placed after alcohol chemistry, approximately alfway through the text. The remaining chapters are devoted to additional synthetic procedures. The text ends with a chapter on the literature of organic chemistry, an introduction to organic qualitative analysis, and a chapter of supple- ental techniques. Four appendices of assorted tables and laboratory calculations conclude the text. Each chapter begins with a theoretical discussion of the chemistry or techniques contained in the chapter. In addition, each experiment in the chapter preceded by a discussion of the practical aspects of the experiment, along with planations of why each reaction or manipulation is performed as it is. Emphasis placed on understanding and doing instead of just doing. The amount of procedural detail in the experiments is reduced as the text progresses. At the start of the book, the steps to be followed are spelled out in detail. The detail provided is gradually diminished as the student proceeds through the course and gains laboratory experience. Toward the end of the text, the experimental detail is similar to that found in research journals. Therefore, the periments in the chapters toward the end of the text call for more student genuity: for example, Experiment 16.4 (Synthesis of an Acetate Ester by a General Reaction Procedure) and Experiment 21.1 (Qualitative Organic Analysis: Selected Procedures).
