Chapter 16, Problem 2Q

1. What type of reaction explains solubility of phenol in sodium hydroxide? Explain the organic product formed. 2. How do the reactions of phenol samples with FeCl3 compare? Which structural component of the phenols account for the observation

3. How would you separate these three molecules from one another utilizing acid/base extractions and ethyl acetate as your organic layer? You can use 10% HC1 (aq.), 10% NaOH (aq.), and 30% NaHCO3 (aq.) as your acids and bases. NH2 HO HO, OH OH ÓH OH

An organic chemistry laboratory Extraction; the extraction of crude naphtalene- benzoic acid mixture. Naphthalene is a suspect carcinogen and is toxic to aquatic life. Find an alternative pair of molecules that adhere better to the principles of green chemistry and can be separated by extraction using green' solvents. (kindly answer fully)

The crude product X obtained is finally purified by recrystallization. You are provided with the following solvents in which product X has the following solubilities: acetone - slightly soluble at room temperature and soluble at boiling, chloroform- insoluble at room temperature and slightly soluble at boiling, hexane-insoluble at room temperature and at boiling, aqueous ethanol - very soluble at room temperature and slightly soluble at -78 °C, methanol soluble at all temperatures. Select the most suitable solvent for the recrystallization of product X giving reasons to justify your choice of solvents. Give your answer in point format.

Suppose you have a mixture of these three compounds. Devise a chemical procedure based on their relative acidity or basicity to separate and isolate each in pure form.

Starting from crude clove oil, draw flow charts to illustrate the extraction steps. Please answer very soon will give rating surely

methyl alcohol and ethyl alcohol are poor extraction solvent. why?
