Hints for identifying compounds in multiple-choice problems (problems 1:5); 1. Closely compare the given compounds. Determine which piece of information (molecular weight from MS, number of peaks in the NMR, presence of a special functional group in the IR, etc) would be the easiest for distinguishing between the given compounds. You might not need to use all types of given spectra to find your correct compound! 2. Based on your answer from step 1, consult the appropriate spectrum first. For...

Worksheet 4: Identification of Unknown Organic Compounds Reading: For a quick video about the "Rule of 13" https://www.youtube.com/watch?v=2YNE7w_GQlo Introduction One of the most important tasks that chemists are faced with is the separation and identification of compounds from mixtures. Gratifyingly, chemists have multiple tools in the quest to identify unknown organic compounds. Infrared spectroscopy is useful for determining functional groups that may exist in a molecule. NMR spectroscopy tells information about the connectivity of...
