Analyzing and Predicting Spectroscopic Data

The interaction of electromagnetic radiation with the structure of molecules in the sample and their study is referred spectroscopy. Several spectroscopic methods are used to acquire sample information, and these methods are proved to be accurate, fast, and non-destructive. The information obtained about the content and composition of molecules from these spectroscopic methods is called spectroscopic data.

14. How many distinct signals are in the ¹³C NMR of the following compound?
Need help, please.
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.
