" Below is a H NMR spectrum of trimyristin (in CDC) (no integrations are shown). On the structure of trimyristin below indicate the hydrogens responsible for the signals: (0.9 points) a) Circle and label with A: all the hydrogens that are responsible for the group of signals from 4.0 10 5.3 ppm do not consider signal splitting only consider information from chemical shift). b) Put in a box and label with B: all the hydrogens that are responsible for the...
Analyze the spectrum below and using the integrations and chemical shifts, assign the protons for the structure shown. Analyze the spectrum below and using the integrations and chemical shifts, assign the protons for the structure shown. If any of the four labels are incorrect, you will see a red X on the top left corner of the spectra. The doublet at 4.1 ppm, upon expansion, shows a doublet of triplets. Explain this extra splitting. The doublet at 4.1 ppm is...
Bellow is the 13C NMR spectra including the integrations of the compound. Show the structure of each (remember from the integration that S singlet, d doublet, t triplet …. So on) Draw the compound structure for each spectrum and show every line belong to which carbon in the molecule Example: Problem (3) molecular formula is: C6H8O (cyclic compound) H O CDClj 100 80 60 40 20 160 140 120 220 200 180 PPM (8)

9. State the divergence theorem. Describe the regions over which the integrations are carried out and the quantities that are being integrated. Consider the vector field 22 V = i ++2k V. V =- i+yj + zk Write the equations of limiting surfaces and their normals of the volume defined by its vertices (1,0,0), (0, 1,0), (-1,0,0) and (0,0,1) which define a triangular pyramid. Calculate the value of the divergence of V for this volume. Use the divergence theorem to...
C8H14. This is an ALKYNE. The relative integrations of the signals are I=3, II=9, III=2. C8H8O2. This singlet at S=3.9 has an integration of 3, and the signals in the S=7-8 region in total have an integration of 5. Draw the structure of the molecule with the given formula that would have each soectra. C8H.4. This is an alkyne. The relative integrations of the signals are 1-3, II = 9, III = 2. 8 3 2 CsH3O..The singlet at 8...
Construct a simulated 1H NMR spectrum, including proton integrations, for CH3CHCl2. Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
