Whether the pure-water bubble or a soap bubble evaporates and pops faster is to be determined. Concept introduction: Surface tension is the tension of a liquid surface that causes due to the attraction of liquid particles in the liquid surface by the liquid particle present in the bulk of the liquid. The surface tension tries to attain a minimum surface area. The formula of surface tension is given by the expression as shown below. γ = w Δ A

Question

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?
