CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings. 1. Your work is unique, meaning that you might be the only person performing certain experiments. 2. Research is an ongoing process. The projects assigned to you will likely continue after you leave. People assigned to those projects will need…show more content…
Examples are the determination of physical constants such as melting point, boiling point, or density, and instrumental techniques such as infrared (IR) spectroscopy. Sometimes these techniques are referred to as analytical techniques. LAB REPORTS FOR CHEMICAL PREPARATIONS, OR SYNTHESIS This type of report refers to experiments whose main goal is to prepare a pure substance from specific starting materials. This necessarily involves a chemical transformation, or reaction. In the simplest case, there is only one step. The starting materials are combined and a product forms. This product is isolated, purified, and characterized, producing the final outcome of the experiment. In a multistep synthesis, the product of the first step is used as a starting material in a second step, and so on, until a final product is obtained. No multistep syntheses are performed in organic lab I. Some two step syntheses are performed in organic lab II. FORMAT AND GRADING CRITERIA FOR PRELABS AND LAB REPORTS The general format for most prelabs and lab reports is given below. Specific differences with examples will be discussed later. You are expected to include the following items in your lab notebook. All prelabs and lab reports are graded on a 100 point scale with the following distribution. INDIVIDUAL PRELAB (100 pts) Due at the beginning of each experiment. 1 NAME, EXPERIMENT #, TITLE, DATE, INSTRUCTOR,
