Question

3.9 Post-lab Questions Empirical chemical shifts derived from a library of model compounds have been used to create a set of parameters useful in predicting the 'H-NMR chemical shifts of a molecule. These empirical parameters are quite accurate provided that the molecule of interest is similar to some of the model compounds used to generate the parameters. Predict the 'H-NMR shifts of the aliphatic, aryl, and vinyl (if appropriate) 'H-atoms of the carboxylic acid in your assigned mixture using the empirical parameters provided on pages V - X. Label each using the assignments on page 3-11. (5 pts) 1) H-atom Empirical Estimate Ppm
