The exam will be on Monday, August 18th from 1:10-2:10. This will be a closed book/note test. There will be a seating chart. A sample exam will be posted on the web site and bulletin board. The exam will be over the Spinach Chromatography, Freidel Crafts acylation, Grignard reaction and the 3 step synthesis. Also review any purification techniques used in these experiments. Spinach TLC Be able to predict relative Rf values for various organic compounds. Know the effect of the solvent system will have on the Rf value. Freidel Crafts acylation Know the structures for all starting reagents, products and possible by-products of this reaction. Know the mechanism for this reaction. Know how you purified your product at the end of the reaction. What purification procedures did you use in this experiment? Know the consequences of water getting into your reaction and how you prevented it from happening. Understand the chromatography behavior of your products. Be able to predict TLC and column behavior of your products. Grignard lab. Know the possible by-products of this reaction. Know the mechanism for this reaction. Know how you purified your product at the end of the reaction. Know the consequences of water getting into your reaction and how you prevented it from happening. Know and understand the strong nucleophilic and basic properties of the Grignard reagent. Know how a Grignard would react with a: ketone, aldehyde, carboxylic acid, and an alcohol. 3 step synthesis: Know the mechanisms for steps #2 and Step #3--the Aldol condensation and the Diels- Alder reaction. Know how to draw all the reactants and products for the reaction. Know how to predict the products of these using different starting materials than what you did in lab. Know the reaction equation for step #1 and the possible by-products of this reaction. For all 3 reactions note how you purified your products—speculate for each step if you could purify the products by acid base extraction, recrystallization, chromatorgraphy or distillation.
