There is a sample chem 242 exam posted on the web site. The test will be over the NMR, IR, Biodiesel lab and the qual anal section of this course. There will NOT be any material on: Mass spectroscopy, Azo Dye, Indigo lab or Paint lab material on this exam. Know the following classification test —Know what a positive test would look like and what functional group it would indicate ( do not worry about mechanisms ). Beilstein test, Ignition test 2,4 – DNP - Chromic acid Bromine test (for phenols and double bonds)— Solubilty tests Ferric hydroxamate test for esters Know the following Reactions: Know the reactions (not the mechanisms ) of the ester hydrolysis and derivatives that use acid chloride chemistry.

Unformatted text preview: NMR and IR . You will be given a table on the back of the test that has listing of NMR and IR absorptions —For NMR it’s the chart on pg 879 in your text-the IR chart will be the one on pg 851 of your text) You will need to identify compounds by interpreting IR, NMR and classification test data (see sample exam). You may also need to be able to draw an NMR if the chemical structure is given to you. For the Biodiesel lab: Know the reaction equation for the synthesis of Biodiesel from vegetable oil. In the reaction 2 layers formed—know what components were in both layers. Know about the property of ‘viscosity’ and why it’s of concern to people who use biodiesel fuels. What information can IR/NMR give you about your biodiesel and its purity?...
