The major product, out of two alkenes obtained by acid-catalyzed dehydration of each of the given alcohols, is to be identified on the basis of Zaitsev rule. Concept introduction: > The dehydration of alcohol results in the loss of molecule and formation of the corresponding alkene. > The H and OH are lost from adjacent carbons. > In case of primary alcohols, only one product is formed, but in case of secondary and tertiary alcohols, there is a possibility of more than one product formation whenthecarbon attached to the OH group is bonded to nonequivalent adjacent carbons. > According to Zaitsev rule, the most substituted alkene is the major product.

Complete the following table. The only density needed is already given. Show your calculations in a neat and easy-to-follow manner in the space below the table. All units should be included and significant figures should be given close attention. Be sure to notice that the amount of material should be in millimoles rather than moles, and the theoretical mass of the product should in milligrams rather than grams. LOCH 3 + H2SO4 HNO 3 O=C-OCH 3 NO2 x H₂O F.W. 4.0 mL 1.3 M amount 0.50 mL in H2SO4 mg Theoretical Theoretical mmoles density 1.09

Kumada Coupling: 1. m-Diisobutylbenzene below could hypothetically be synthesized by Friedel-Crafts reaction. Write out the reaction with a mechanism and give two reasons why you would NOT get the desired product. Draw the reaction (NOT a mechanism) for a Kumada coupling to produce the molecule above from m-dichlorobenzene. Calculate the theoretical yield for the reaction in question 2 using 1.5 g of p-dichlorobenzene and 3.0 mL isobutyl bromide. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?

Wintergreen from Aspirin: 1. In isolating the salicylic acid, why is it important to press out as much of the water as possible? 2. Write the mechanism of the esterification reaction you did. 3. What characteristic absorption band changes would you expect in the IR spectrum on going from aspirin to salicyclic acid and then to methyl salicylate as you did in the experiment today? Give approximate wavenumbers associated with each functional group change. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material?
