Explain the NMR patterns for protons Hc and Hd shown in Figure 2. (Hints: These protons are nonequivalent because of their location adjacent to a stereocenter. The 2 J coupling constants for protons attached to an sp3 carbon are very large—in this case, 16.5 Hz. The 3 J coupling constants are not equal. Draw a sawhorse projection for the molecule. Can you see why the 3 J coupling constants might be different?) Apr 24 2022 07:38 AM
