• Reagent Table: List the properties for each compound (MW, bp/mp, density, safety notes). • Written Procedure, as described below. Include 3 IR tables, one for each compound, where at least the first 4 columns are completed. You will not be permitted in the lab without these tables! • Safety & Cleanup: Copy table into your notebook.
