Please Help Do Not forget to explain please! Worksheet 4: Identification of Unknown Organic Compounds Reading: For a quick video about the "Rule of 13" https://www.youtube.com/watch?v=2YNE7w_GQIO 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...
