Based on the spectra provided, draw the structure. Label each unique carbon and hydrogen with the letters A, B, C… for use in assigning NMR peaks. fill in the data table assigning peaks in each spectrum. You should assign: • All 1H NMR peaks • Significant IR peaks above 1600 cm Example of what the table should include (imagine the structure of ethanol is drawn with the CH3 hydrogens labeled as A, the CH2 hydrogens labeled as B, and the OH hydrogen labeled as C) :  hydrogen proton chemical shift  integration splitting pattern couples to.. A 1.2 3 triplet B B 3.7 2 quartet A C 2.6 1 singlet -

Identify the following spectra. Assign all pertinent peaks (~5-6 peaks). Place the structure of the compound in the box on the lower left-hand corner of the spectrum. circle spectrum on graph

See image below

A.) How many signals are seen for the CNMR spectrum of the unknowns C6H14O? B.) Explain the chemical shifts of the signals seen based upon the location of the carbons that are relative to deshielding group if any are seen in the compound (unknown is C6H14O)?  For question A. I believe it is 4 signals. For question B. I know that none of the signals are in the deshielding are of the chart but are all located in the shielded region but i am unsure of how to determine the chemical shifts of the given signal. If possible an in-depth explanation would be greatly appreciated in order to understand this better.

Identify the following spectra. Full credit is only given if all pertinent peaks are assigned on the spectrum (~5-6 peaks). Label the peaks on the spectrum and place the structure of the compound in the box on the lower left-hand corner of the spectrum (from the table below, no numbering scheme). It is highly advisable to use the tables provided in the infrared handout and lecture to avoid confusion caused by tables from different sources. You do not have to indicate the exact wavenumber of the peak. please circle the peaks on the graph

Arrange the following compounds in their correct order of chemical shift (). 1=Highest and 4=lowest. (All show just one signal in their 1HMR spectrum).
