You will have to perform all the steps necessary to separate your assigned compound from its impurities and prove through analysis (melting point, boiling point (if applicable), NMR, IR and Rf-values (if applicable)) that your compound is pure: An organic student was trying to purify acetaminophen from Advil but the extraction using dichloromethane yielded a mixture of caffeine and acetaminophen. Purify the acetaminophen. Provide data to show that your compound is pure. Materials Available to you: Solvents: acetone, ethanol, methanol,...

Exercise 1 - Questions 1. Define physical and chemical properties and give at least 3 examples of each type of property. 2. Which substances in Data Table 1 have melting points below room temperature? Are these substances more likely to be ionic or molecular compounds based on melting point alone? Explain. 3. Which substances in Data Table 1 have melting points above room temperature? Are these substances more likely to be ionic or molecular compounds based on melting point alone?...
A compound with the molecular formula of C7H16 has the following physical properties: mp= -123.8 C; bp= 79.2 C; density = 0.6739 g/mL. There are several compounds with that formula. Use a reference book to determine the name and the structural formula of the isomer with those specific properties. Hint: Use the boiling point index at the end of the section “Physical Constants of Organic Compounds” in the CRC Handbook of Chemistry and Physics. Determine the boiling point, water solubility...
Backgrouund: Material Safety Data Sheets have been prepared for each commercially available chemical compound. There are several sources for MSDS information. In our lab we have hard copies in yellow MSDS binders. We also have the Aldrich Chemical Catalog, the CRC Handbook of Chemistry and Physics, and the Merck Index. Using a search engine, you can also enter the chemical name along with "MSDS." Also, when looking up a particular compound, make sure that you are getting the actual compound...

Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...
