- Why is it more difficult to recrystallize benzil when using hexane as a solvent instead of ethanol?This experiment is the Separation of a mixture of 3-nitroaniline, Benzoic acid, and naphthalene using an acid-base separation extraction technique What properties of the three compounds in this experiment allow you to use the above technique to separate them?Why are you asked to use multiple portions of the solvent at the extraction steps?Why are you asked not to discard any solvents until you have obtained your products?2. In this experiment, you used ethyl acetate as the initial solvent to dissolve your mixture of benzoic acid, 4-bromoacetophenone and ethyl 4-aminobenzoate. i) Explain 3 reasons why ethyl acetate a good choice for this process? ii) Would you have obtained similar results with A) chloroform, B) ethanol, or C) water? Why or why not? Explain. Hint: Think about both solubility and miscibility of solvents when answering your question.
- How would you recrystallize a mixture of Benzoic acid and 2-Naphthol? Discuss the choice of solvent and recrystallization process. (Hint. Look up the solubility of these two compounds in different solvents)steps in purification of the mixture of benzoic acid and benzaldehydePropose a method to separate a mixture containing phenol, benzoic acid, naphthalene, and p-nitroaniline. Phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in either sodium hydroxide or sodium bicarbonate solutions. Write out the structures of the molecules in your scheme.
