Post Laboratory Questions: Please answer the following questions on a separate sheet(s) of paper. You may neatly handwrite or type your responses. They will be collected at the beginning of the next laboratory period. Late responses will receive half-credit. Part A: Use the data collected using 4-t-butylphenol, draw a graph of the retardation factor vs. solvent composition. Interpolate the data points (i.e. draw a smooth line through them). Is the relationship between Rf and solvent composition linear? Suggest a reasonable explanation for your results. A student identified some white crystals located in an unlabeled flask that his lab partner had just purified via chromatography. Based on his partner's lab notes, he is certain that the unknown is only one of two known compounds, 4-t-butylphenol or 1,4- dimethoxybenzene. In the space below, describe a simple experiment that would allow the student to determine the identity of the unknown. Part B: Calculate the weight percentage of ferrocene and acetylferrocene in your metallocene mixture using the data collected. Part C: In today's experiment, a chromatographic purification of multiple organic compounds was performed. Based on your experience, which of the following physical properties (boiling point, density, solubility, or melting point) do you think causes/allows chromatography to work? Explain your reasoning. Calculate the weight percentage of fluorene and fluorenone in your mixture using the data collected.
