- In the reaction of the phenol nitration, a mixture of o-nitrophenol and p-nitrophenol is formed. The melting point of onitrophenol is 450C, the melting point of p-nitrophenol is 1120C. How would you interpret this difference depending on their molecular structure?One of the components of nutmeg is an organic compound, Trimiristin, A. To extract this compound from nutmeg why we need to choose as a solvent, ether, and not acetone?B. Is it possible to choose water as an exhaustive solvent of Trimiristin?In the reaction of the phenol nitration, a mixture of o-nitrophenol and p-nitrophenol is formed. he is- The melting point of nitrophenol is 45, the melting point of p-nitrophenol is 1120C. How would you interpret this difference depending on their molecular structure?
- Isopropanol is a good extraction solvent for plant pigments as it breaks down cell walls and is miscible with pigments. Can you be sure that you only extracted chlorophyll-a from your spinach leaf? If not, what else might have been extracted?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 extractionsHow do you prepare a 100mL solution of 5% acidified methanol?
- I need help figuring out the quickest way to separate the mixture between biphenyl and ether. I don't where or how to start this problem?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?Absolute ethanol (100% ethanol, with no water) cannot be obtained through simple fractionaldistillation because of the lower boiling azeotrope that forms with water. Propose a method by which onemight prepare absolute ethanol
