2 PLAN OF THE SEMESTER'S PROGRAM The goal for the first semester of the organic chemistry laboratory program is to introduce the basic laboratory techniques underlying all laboratory work in organic chemistry. These techniques illustrate the methods that are used to carry out and "work up" a reaction. "Working up" a reaction refers to the procedures used to separate the components of a reaction mixture, purify the desired product and characterize the substance. These techniques will then be used to carry out some typical transformations, which reflect the reactions of some functional groups found in organic molecules. Learning Objectives Chemistry 2153: Demonstrate proficiency in organic laboratory techniques, including methods for the separation, purification, and characterization of organic substances. Interpret experimental observations and draw conclusions about the outcome. Summarize and explain observations in a coherent laboratory notebook. Apply the laboratory techniques learned to a set of typical organic reactions. Calculate reaction yields and evaluate the relative success of reactions. Apply safe laboratory practices and proper chemical hygiene to all operations. REQUIRED TEXTBOOK Experimental Organic Chemistry: A Miniscale Approach - GWU Edition By R. M. Roberts, et. al., Harcourt Brace Custom College Publishers SCHEDULE OF EXPERIMENTS The following is the schedule of the experiments for the semester. All references for reading assignments, experimental procedures and exercises are to this Laboratory text. In addition we have provided supplemental information in this document in order to improve and adapt the experimental
