The Following Problem Set Presents Data For The H Nmr Spectrum For An Unknown Compound Using The Spectroscopic And Ana 1 (388.88 KiB) Viewed 51 times

The following problem set presents data for the 'H NMR spectrum for an unknown compound. Using the spectroscopic and analytical data, you should attempt to suggest a structure which is consistent with the data; it will often be impossible to generate a unique structure based on the NMR alone. Review materials are available through the MENU above and "hints" and interpretations are provided for each spectrum. You should attempt to work the spectra in order; you may, however, jump to any problem in the set by clicking on the problem number below. Clicking on the "Begin" button will take you to Problem #1.
