Examples of Required Writing Assignments

Pre-Lab write up of the experiment which includes the reagents used, stoichiometry, detailed procedure of the experiment. Diagram of experimental set-ups. Waste disposal. Lab report: Data (quantities of reagents used, products obtained, and their physical properties). Calculation (% yield). Discussion must mention techniques used (i.e. distillation, M.P. TLC, extraction), purity of the product (using IR spectroscopy). Sources of error.

Examples of Outside Assignments

Critique of the results of the experiment by figuring out the structure of the product. A multi-step procedure of compound X is assigned. The identity of compound X and the mechanism of its formation must be explained.
