Science Homework Help

1) What can you determine about each product from its respective FTIR and H NMR spectra? Can you identify the compound due to the presence of FTIR absorption bands particular to a specific functional group (or the lack thereof)? Can you identify each compound from the hydrogen spin-spin splitting patterns, integrations, and chemical shifts of its peaks? Give a detailed analysis of the H NMR spectra you obtained in lab. Be sure to include a detailed mechanism for each of the acid/ base conversions that take place during the experiment. In addition, provide a detailed flowchart that shows how each component was isolated during the course of the reaction. Use the flowchart provided in the techniques section as inspiration.

3) Would it make any difference if the methylene chloride solution containing both the basic and neutral components was washed with 1M sodium hydroxide rather than 1M hydrochloric acid? If so, what would that difference be? Would any layer separation be possible in the new solution? Would it be possible to isolate the two components from one another using 1M sodium hydroxide rather than 1M hydrochloric acid? Why or why not? Provide a balanced equation to justify your answer solutions. Use skeletal structures only in your answer:
