On the following page, you will find the IR, ¹³C-NMR and ¹H-NMR for C₆H₁₂O. Determine the structure of the molecule. As you solve the structure, keep the following questions in mind:- What is the index of hydrogen deficiency for this formula?- Using the IR, what functional group(s) is (are) present in the molecule? What functional groups are missing?- At what chemical shift range should look for corresponding peaks in the CNMR? In the HNMR? Are there peaks in those regions?- How many peaks are in the carbon NMR spectrum? How does it compare to the chemical formula? What might this tell you about the molecule?- How many peaks are in the proton NMR spectrum? How does it compare to the chemical formula? What might this tell you about the molecule? ### Chemical Analysis of C8H12O#### Infrared (IR) Spectrum:The first graph displays the IR spectrum of the compound with the molecular formula C8H12O. The x-axis represents the wavenumber, ranging from around 4000 cm-1 to 500 cm-1. The y-axis shows the transmittance percentage. Key peaks are typically indicative of functional groups, though specific values are not labeled.#### Nuclear Magnetic Resonance (NMR) Spectra:##### Carbon-13 NMR Spectrum:The second graph presents the Carbon-13 NMR spectrum. The x-axis is labeled with chemical shifts in parts per million (ppm), ranging from 220 ppm to 0 ppm. Peaks appear at several positions which indicate different carbon environments. Observing the number of peaks can provide insights into the number of distinct carbon atoms present in different environments within the molecule.##### Proton (1H) NMR Spectrum:The third graph shows the Proton NMR spectrum. Here, the x-axis also represents the chemical shift in ppm, typically from 0 to 10 ppm. Notable peaks and multiplicities include:- A multiplet around 1H labeled "m"- A singlet peak at 3H labeled "s"- A doublet at 2H labeled "d"- Another doublet at 6H labeled "d"The integration numbers beside the peaks indicate the relative number of protons contributing to each signal.These spectra collectively help identify the structure and components of the compound C8H12O, aiding in functional group identification and understanding the chemical environment within the molecular structure.

For each of the ten spectra, you should determine which peaks are the most important for identification purposes, what their wavenumber values are, and what specific bonds and/or functional groups they indicate. Record those in the spaces under each spectrum. You don’t have to use each space. Then, from the list of possible compounds, identify what compound is responsible for each spectrum. Realize that these are all the real samples and there may be impurities present that cause weak peaks which would not normally be caused by the compound, such as the one at 3450 cm-1 in Spectrum 1.

1. List the integration of all peaks as a ratio. For example, 4-hydroxy-4-methyl-2-pentanone would have a ratio of 1:2:3:6.How does the integration of the peaks correlate to the number of hydrogens present in the molecule? 2. For each peak, draw a partial structure that uses all three pieces of information (chemical shift, integration, splitting patterns). Make sure that you highlight the hydrogen atom or atoms that are responsible for the signal. An example of this is: -CO-CH2-CR2- 3. Based on the chemical shifts, what functional groups are present in your compound? For each, correlate the functional group with the chemical shift of the identifying peak.
