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…

A.) How many signals does the HNMR of the unknown C6H14O have? B.)Whats the ratio between the number of different hydrogens in the unknown compound C6H14O? C.)Explain splitting patterns of all the signals (in depth if possible the lecture confused me). D.)Explain the chemical shifts of the signals based upon the locations of hydrogens relative to the desheilding groups if any are present in the compound. For A. I think there are 4 signals. For B. I think the ratio is 1:1:3:9 for the hydrogens on the HNMR spectrum. For the last 2 questions (C. and D.) the lecture confused me so an in depth of how you found the answer would be greatly appreciated. Also the unknown for the attached HNMR is C6H14O.
