Chemistry 241 Spring 2010 Mike Holden Lab 6 USE OF TECHNOLOGY FOR ORGANIC CHEMISTS This laboratory is heavily dependent on, and inspired by, “Technology for the Organic Chemist: An Introductory Laboratory in Three Modules” by Esteb, J.J.; McNulty, L.M.; Magers, J.; Morgan, P.; and Wilson, A.M. submitted to J. Chem. Educ., 2009. There are several technological tools available to organic chemists, and scientists in general. These tools continue to change and evolve. It is important for scientists to be aware of the resources available to them for up-to-date research, scientifically appropriate databases, and professional presentation of scientific data. This laboratory will introduce you to only some of the tools available to you. A lab period has been set aside as time to complete this assignment. You are not required to complete this assignment during laboratory time, but the instructor will be available during lab hours for questions. Part 1: Research Tools Online resources for the research scientist are invaluable, so long as the sources are appropriate, reputable, and scientific. Websites like www.chemfinder.com and www.sigmaaldrich.com contain a great deal of information. You will be utilizing these sources in various activities common to synthetic chemists. EXPERIMENTAL PROCEDURE: Log into your chosen computer and open your favorite web browser. Be sure to turn off the “pop-up blocker” in your browser as many of the items you will be calling up show up in pop-up windows. Note the web browser that you are using. Access the list of sites that you will use by opening the following site: http://delicious.com/holden8758/241techlab (this is the “useful links” link on the lab tab of the course ning site) Open the ChemBioFinder site and do a search on “aspirin.” General information about aspirin should appear, showing the structure, molecular formula, molecular weight, CAS (Chemical Abstracts Number), density, melting point, and boiling point. Note all of this in your notebook. Lower on the page, there are several links to sites of interest about aspirin. Click on two of them. What did you find? What information about aspirin do you now have? Go back to the chemfinder search page. What chemical compound, medication, or drug would you like to know more about? Type in the name of that item and perform the search. What did you choose? Note all the general information (see the list for aspirin). Are

there other sites of interest for your compound? Go to two if you are able. What did you find? What additional information do you have? Much of the same information that could be found on ChemBioFinder in the past can now be found on wolframalpha. This is a “computational knowledge engine” that seeks to deliver information on a topic, rather than present a listing of other web sites that may be useful. Search for aspirin and record some of the information that you get. Wolframalpha is a good site for a variety of uses. Type in today’s date and see what information you can get.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
