- 4.It is tempting to maximize the amount of product isolated by continuing the fractional distillation until no solution remains in the distilling flask. Why is this not done?If 80% of a desired compound is extracted into the organic phase in each step (leaving 20% in the aqueous layer), how many extractions are necessary to ensure that at least 99% of the compound has been recovered in the organic phase? 1 extraction 2 extractions 3 extractions 4 extractionsWhat is the dominant intermolecular force that governs the solubility of 9-fluorenone in methylene chloride?
- Why the Refractive Index of hexane and heptane from simple distillation closer to the refractive index of hexane and heptane from fractional distillation?There should be a difference in your results between the solubilities of benzophenone in methyl alcohol and benzophenone in hexane. Explain this difference.A student recrystallized some impure benzoic acid and isolated it by filtration. He scraped the purified benzoic acid off the filter paper after it had dried and took the melting point as a test for purity. He was surprised that most of the white solid melted sharply between 121 and 122 °C but that a small amount remained unmelted even at temperatures above 200 °C. Explain this behavior.
