Brittney Brown Due: 10-15-2009 Title: Unknown Identification Lab Partner: Chelsea Searels The purpose of the of the unknown identification experiment was to analyze the unknown organic compound labeled SSQ and determine possible functional group and structure using data from the infrared spectroscopy, 1 H NMR, and a series of functional group tests (1). Experimental Details: Table 1. Substances used in the experiment and the amounts Substance Amount Water 1 mL 5% HCl 1 mL 5% NaOH 1 mL Br 2 in CCl 4 2 drops Chromic Anhydride 2 drops DNP reagent 2 mL AgNO 3 2 mL NaOH 1 drop 5% NH 4 OH Until dissolved The lab was split into two weeks. For the first week, the unknown organic compound labeled SSQ was obtained. One drop of the sample and one mL of the solvent, chloroform were mixed in order to obtain the 1 H NMR. The next week, five functional group tests were performed. The first functional group test performed was solubility. The solubility consisted of mixing 1 drop of the unknown sample with 1 mL of water to test for possible polar functional groups. Next, the sample’s solubility was tested in 5% HCl and 5% NaOH. The Bromine test was performed next using 5 drops of the sample and 2 drops of the reagent Br
