3) The position of the OH resonance of phenol varies with concentration in solution, as the following table shows. On the other hand, the hydroxyl proton of ortho- hydroxyacetophenone appears at 12.05 ppm and does not show any great shift upon dilution. Explain. Phenol o-hydroxyacetophenone Concentration w/v in CCl (ppm) 100% 7.45 20% 6.75 10% 6.45 5% 5.95 2% 4.88 19% 4.37

    Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
