Interpreting NMR spectra is a skill that often requires some amount of practice, which in turn, necessitates access to a collection of NMR spectra. Virtual Chemlab Organic has a spectra library containing more than 700 'H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish...
