1. Interpreting the Table 1. For the following exercise, reference Figure 13.8 in your textbook or e-book, and watch the video for that figure in the e-book, For each labelled proton, indicate the ppm range you would expect to find it in for an NMR spectrum. Don't over-think it, just use the chart at this point (Note: In many cases, especially in biochemistry, there will be many complicating factors - here we are just looking at the simple model). CH...
