Determine integration, and splitting you are expecting in the 'H NMR. Step 1: Look at the integration and splitting of the signals in the H NMR spectrum - assign the chemical shift of the protons of the methyl group; make a note which signals in the 'H NMR are due aromatic protons, NH and/or OH. Step 2: Look at the 'HSN HSQC spectrum - Use this spectrum to assign the chemical shifts of the NH proton and the OH proton. Step 3: Look at the 'H1SN HMBC spectrum - Use this spectrum to assign the chemical shifts of the aromatic protons in the 'H NMR. Step 4: Look at the 13C NMR spectrum - Make a note which carbon atoms are aromatic and/or alkyl. Assign the chemical shift of…

Splitting of a signal in a proton NMR spectrum tells us the number of chemically non-equivalent hydrogens in the inmediate vicinity of the hydrogen giving the signal. Predict the number of lines exhibited by hydrogens at the labeled positions in a first-order NMR spectrum. (Make the approximation that all coupling constants are equal.) 1) The number of lines exhibited by hydrogen(s) a is The number of lines exhibited by hydrogen(s) b is The number of lines exhibited by hydrogen(s) c is Br 2) The number of lines exhibited by hydrogen(s) a is The number of lines exhibited by hydrogen(s) b is The number of lines exhibited by hydrogen(s) c is
III) Can 1H NMR spectroscopy be used to differentiate between the two compounds? Briefly explain why or why not. Predict the 1H NMR spectrum for each compound (include integration, multiplicity, and approximate chemical shift). For each set, be sure that you put them in a data table format!
Part 5: Putting It All Together We don't quite have all the parts of an NMR analysis yet, but we can go a long way to solving the structure of a molecule just by considering the number, chemical shifts, and in the case of 1H NMR, the integrals of the signals. In the next pages, a compilation of 'H and 13C NMR spectra are shown for all but one of the organic compounds shown below. Your job is to match the compound with the spectra. Don't just write the structure, some justification for your choices must be given as well. `NO2 HO NO2
Stannous fluoride, or Tn(1l) fluoride, is a compound commonly used in toothpastes with similar in function and activity to sodium fluoride (NaF), the conventionally added ingredient in toothpastes, but has been shown to be more effective.
