NMR Practice Problems. In the following examples, we will learn how to solve NMR practice problems step-by-step in over 100 min video solutions which is essential for organic structure determination.
The advanced spectral analysis problems focusing on analyzing 1- and 2D NMR spectra to address questions of stereochemistry. The advanced structure determination problems focus on using all of these techniques to determine the structures of organic compounds.
Winter 2016. (Problems from former Chem 30BL finals) 1. Compound W has an empirical formula of C11H10O2. Given are the following spectra. Show all your work (= label peaks in the spectra!) Determine the degree of unsaturation for the compound. Assign the six pertinent peaks in the infrared spectrum.
Spectroscopy Problems. In each of these problems you are given the IR, NMR, and molecular formula. Using this information, your task is to determine the structure of the compound. The best approach for spectroscopy problems is the following steps: Calculate the degree of unsaturation to limit the number of possible structures.
Online NMR Practice Problems and Resources. Some good resources to practice NMR problems and combined spectral problems (ones that have proton, carbon, and sometimes IR and MS data) are listed below. The first site has tons of practice problems at all levels, from beginning to advanced.
1H & 13C NMR SPECTROSCOPY QUESTIONS. with molecular formula C6H14O are shown. The relative integration values for the NMR peaks are shown on Figure 2. Deduce the structure of compound R by analysing Figure 1 and Figure 2. Explain each stage in your deductions. Use Table A and Table B on the Data Sheet
W has an empirical formula of C10H13NO2. Given are the following spectra. Determine the degree of unsaturation for the compound. Assign five pertinent peaks in the IR spectrum. Suggest a structure for compound W based on the spectra given.
