Problem Set 1 – 1H NMR Spectra. The IR and 1H NMR spectra of a compound of molecular formula C10H12O are given below. SDBSWeb: http://www.aist.go.jp/RIODB/SDBS/ (22-12-09) Calculate the degree of unsaturation. x 10 – 12 + 2)/2 = 5.
The following exercises are designed to help you become familiar with predicting the 1H NMR spectra of simple organic molecules. For each example you should find the number of signals you expect, where they should show on the scale (chemical shift), and what shape they should be (splitting patterns).
Chemistry 233 Chapter 13: NMR Spectroscopy Problem Set. 1) For each compound below, identify each chemically distinct type of hydrogen. Specify the number of 1H NMR signals you would expect to see. 3) Consider the indicated protons in each of the three compounds below.
