In this short search assignment, you will be looking for certain specific chemical information about a substance. All the substances in the master list below are used as chemical solvents. The databases you use for this assignment can be found primarily on the Chem 350 website or GMU Library databases.
Choose your substance in the list below according to your computer number. If you have trouble completing this assignment with your assigned compound, please let me know immediately.
Remember -- it is almost always better to search using a registry number or molecular formula than substance name. So....
Begin by going to the Dictionary of Organic Compounds to obtain some basic property information about your substance. Enter the name of your compound and press the Search button (don't press "browse"). Open the details window for your compound. Print the first page. (At some point in this assignment you might need an isomer of your substance. This is a good place to find isomers from the molecular formula.)
Go to the ChemExper database to search for commercial availability of your chemical. Print the first page. On the page, make a brief comparison of commercial sources as you found here v. the Dictionary of Organic Compounds.
At the top of the page, click "New: Predict NMR Spectrum". You will be taken to a new page. Be patient, and the spectrum should appear in the box. Press "Print Report".
Go to each of these websites and try to find the information that is specified.
SDBS Find the H-NMR spectrum (If it is not available, use an isomer of your substance. Please note the name of the alternate substance on the printout.) Using the same procedure as you did in Assignment 1, print only the spectrum frame (right-hand frame). (The procedures are slightly different depending on whether you use IE or Firefox.)
On the page, make a brief, handwritten comparison about the output NMR from this source vs. the predicted spectrum, above.
National Institute of Standards and Technology
[Use the NIST Data Gateway in the right frame.] Find thermodynamic data in the NIST Chemistry Webbook.
Choose a link under "Other data available" such as Phase change data (best) or Condensed phase thermochemistry data, etc. Print the first page and the page that has your chosen data on it. [If there is no data for your compound, use your compound's molecular formula to search for data on an isomer. Please note the name of the alternate substance on the printout.]
Organic Syntheses Database (Wiley) Find a reaction involving the substance.
The easiest approach to this comprehensive reaction data base is to choose "
[If there is no data for your compound, use an isomer of your substance. Please note the name of the alternate substance on the printout.]
Material Safety Data Sheets The best source for MSDS is the manufacturer of the substance. Two common manufacturers of lab chemicals are Sigma-Aldrich and Fisher but there are others. Print the entire MSDS. [If there is no data for your compound, use an isomer of your substance. Please note the name of the alternate substance on the printout.]
Assemble and staple your printouts in the order in which they are mentioned in the assignment. Submit printouts separately from the SFS assignment. There are no electronic files to submit.
