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...

Spectroscopy Problems For each problem, you must: 1) Calculate the degree of unsaturation. 2) Assign the principal IR absorption bands above 1500 cm-1 3) Draw the structure of the compound 4) Label the protons on your structure with letters and assign them to peaks on the NMR spectrum (see the example below). в OHD 3.5- 3. 2.5 1.0 PPM 0.5 Each problem contains the formula of the compound, the IR spectrum (with axes in cm vs. % transmission), and the...
Organic Chemistry - Using the following IR anaylsis identify the major peaks and possible functional group identity. Using the two NMR spectra, discuss the integration of peaks, chemical shifts, and splitting. Using the mass spectra, identify molecular weight and important fragments to confirm the structure. Draw the fragments that correspond to each peak in the mass spectra. Draw the structure of the unknown that corresponds to all available data. additional information: Unknown ‘J’ is a alkane. H-NMR multiplet, 1OH triplet,...
