Hexanoic acid was added to an immiscible biphasic solvent system, water and CCl4 at 20.0OC and the equilibrium concentrations of hexanoic acid were determined to be 3.66 g/L in H2O and 67.0 g/L in CCl4. Caluclate the distrubution coeffiecent (D2) of hexanoic acid in water with respect to CCl4.

Your employer hands you a heterogeneous mixture and asks you to isolate all of thehexane that you can from it. After some analysis, you determine that the mixture contains toluene, hexane,benzoic acid, water, sodium chloride, and sand. Explain how you would isolate pure hexane from thismixture. Remember that you can use techniques such as filtration, extractions, and acid/base chemistrythat we learned earlier in this course in addition to distillation. You may need to look up solubilities and/orboiling points online to solve this problem. You only need to isolate the hexane?

6.0 mL of cyclohexanol, 8 mL of 85% phosphoric acid, and 10 drops of sulfuric acid are added to a 50-mL round-bottom flask with boiling chips, and the mixture is distilled into an ice-cooled receiver. The distillate is in the form of a colorless bi-phasic mixture. The cyclohexene upper layer is removed from the water layer, and dried over anhydrous calcium chloride. Isolated is cyclohexene as a clear and colorless foul-smelling liquid. Weighing data is given below. Gross mass: 51.24 g Tare mass: 48.04 g Product mass: 3.2g Question:  Calculate the theoretical mass of the cyclohexene product, bearing in mind that the cyclohexanol starting material was measured by volume, not by mass (so you must use the density of cyclohexanol to convert milliliters to grams, before calculating the number of moles). Calculate the percent yield of cyclohexene obtained.

17. 1-Octanol is immiscible with water. Consider the octanol/water distribution constants for a. series of 1° alcohols: 国 Compound [compoundJoctanol[compound]water HO, HO, 34 107 HO, 370 HO, Based on this data, which statement is true? (a) "The relative ease with which an organic compound is extracted out of water depends only on the polarity of the functional group present." (b) "The relative ease with which an organic compound is extracted out of water depends on the ratio of nonpolar to polar groups in the molecule." (c) "Whether an organic compound is extractable from water is not predictable based on structure." Focus English (United States)

What would the % yield of ester be if the reaction were simply allowed to equilibrate (i.e. no products are removed)? C3H7OH+C2H5COOH=C6H12O2+H2O Percent yield of ester was 71.6% weight of product= 20.7868g 19.0mL (0.25mol) of n- propanol 18.5 mL (0.25 mol) of propionic acid At room temperature, the equilibrium constant, Keq is approximately 3.
