Anything from General Chemistry or CHM 2210 covered up until now.
Any problems like those assigned from chapters 12 and 13 on topics covered in class.
Explain what's going on at the molecular or sub-molecular level for each of kind of spectroscopy commonly used by organic chemists:
What kind of structural information is obtained from each kind of spectroscopy above?
From a mass spectrum identify the compound's molecular mass and possibly which of several isomers it is.
From a molecular formula containing any number of carbon, hydrogen, nitrogen, oxygen, and halogen atoms, deduce how many rings and or pi bonds are in the structure. (i.e., Determine the degree of unsaturation.).
Identify the reasonable molecular formulas that match a given molecular mass.
Define the terms "molecular ion" and "base peak" and be able to identify these in a mass spectrum.
Predict the most likely of several possible mass spectral fragmentation patterns for a given compound based on relative stability of carbocations and free radicals.
Know the various regions of the IR spectrum:
Using a table of IR absorptions (provided if needed), match compounds with their IR spectra.
Assign one or two key peaks in an IR spectrum.

Which nuclei can and can not be observed by NMR?
Define, use, or recognize the following terms:
Identify the number of different hydrogen environments for a given compound and use that information to predict the number of possible signals in a proton NMR spectrum.
Have a general sense of what kind of hydrogen environment corresponds to the various chemical shift regions of a proton NMR spectrum.
Interpret the integration numbers in a proton NMR spectrum. What is the significance?
From the splitting pattern in a proton NMR spectrum, deduce the number of coupled nuclei for each signal (recall n+1 splitting)
Predict the number of signals, the approximate relative chemical shifts, the relative intensities of the signals (integration), and the coupling patterns (multiplicities) for the hydrogen NMR spectrum of a given molecule.
How is 13C NMR like 1H NMR? How are these different?
Identify the number of different carbon environments (i.e., the number of expected peaks in the 13C NMR spectrum) for a given compound.
What three experiments are done during the DEPT technique? Explain briefly what information can be obtained from DEPT spectra. Interpret a given DEPT spectrum and use it to help deduce a structural formula.
Deduce an unambiguous structural formula for a compound from spectral data provided.
