Below is the H NMR spectra for the molecule styrene. Consider if a hydroboration reaction was preformed on styrene. How would the H NMR of the expected product change in comparison to styrene? Circle which peaks from the styrene spectra would disappear and not be present in the NMR of the product. Draw the expected product. Describe the splitting pattern of each new proton signal that would appear in the NMR of the product. 2) Below is the 'H NMR...
2. Predict the number of signals and the splitting pattern (s,d,t, etc) for each of the hydrogens in the 'H NMR spectrum of the compound below. (14 points) CH3 -CH2-O-CH3 2. Design and draw the X and R charts using the following data based on a sample size of seven items. Five samples were taken and inspected. The means of those samples were 21.6, 20.5, 19.9, 20.8, and 22.1, and the sample ranges were 5.6, 5.0, 3.8, 2.2, and 4.5.
II. Number of Signals 2. Predict the number of unique protons that would generate peaks in an NMR spectrum. Look at Figure 13.6 and example problem 13.2 for guidance. Then for each of these unique proton signals, predict the ppm range where you would find it and the integration value or signal area. Look at figure 13.7 in your textbook. Finally, determine the splitting pattern (multiplicity) of the signal. This is predicted using the n+1 rule. Watch the video for...
