Purpose: Write a 1-2 sentence statement detailing the purpose of the laboratory experiment. You need to be specific about which main the reagents will be used and what product is being attempted to be made. e.g. The Diels-Alder reaction will be studied. Maleic anhydride will be reacted with 1,3- butadiene to form cis-4-cyclohene-1,2-dicarboxylic anhydride Chemical Equation: Write any equations used in this experiment. This includes a balanced chemical equation of the reaction that is being studied. Draw the molecules associated with the key reagents in the lab. e.g + - Mechanism: If applicable: e.g. estic m 3 E e.g. Reagent Table: Calculate the amounts of materials needed (as applicable) and the theoretical product yield. Note the relevant physical properties of chemicals used. The table should include melting point (for solids), boiling point and density (for liquids), molecular mass, amount used and moles used (for reactants, product, and solvents). Data does not need to be reported for reagents used to clean up the reactions (these are usually the reagents used at the end of the reaction and are often acids & bases or drying agents). The following are good Name Moledular Weight M.P (if solid) B.P (if liquid) Density liquid) (if Amount Used Moles Used in g or ml Butadiene Maleic Anhydride Solvent used During reaction Product Pre-lab questions: Please number as in the book. These questions will be assigned for each week through blackboard. Procedure with observations: Highlight the Unknown ID. Write the procedure in a bulleted format. This needs to reflect what you did and not what the book states, as often you will make adjustments. Observations must be included at each step; these include color changes and description of the product. Include the procedure of the experiment where things went wrong. It is expected that you write the procedure out as you are doing your experiment. Always include a diagram of the setup of your apparatus. If you do a m.p. state that is was done in this section and include the mp data. Also report what other characterization methods were done. Data and Calculations: Show calculations for % yield (include theoretical and actual). Know how to calculate % yield. This should be reported for all labs were a chemical is synthesized. Report m.p./b.p., analysis of IR/NMR and refractive index. For all calculations show clear work, Procedure with observations: Highlight the Unknown ID. Write the procedure in a bulleted format.

Report m.p./b.p., analysis of IR/NMR and refractive index. For all calculations show clear work, including the mathematical equation. Sources of Error: Sources of error should be included. eg What could have improved the yield? Why were the MP/BP or RI not what as expected? What went wrong or could have been improved Conclusion: Was the purpose of the experiment met? State the evidence you are using to support your conclusion. If the experiment does not work out as intended, then state what happened and why you think the experiment went wrong in your opinion; also state what you expected to happen. You must identify your unknown. Results & Conclusion Questions and Critical Thinking Questions: These questions will be assigned each week through blackboard.
