In this NMR handout, you will get practice interpreting NMR spectra. Refer to the NMR tutorial/theory for chemical shifts and descriptions of peak splitting. There are 4 NMR problems. For each problem, you have been given the chemical formula as well as the IR and NMR spectra. Draw the structure for each unknown compound and provide sufficient reasoning as to why you think it has that structure. To get full credit, determine the structure of the unknown compound, calculate the...
Need help proposing a structure given the following
data. thank you.
