1) In the empty boxes, indicate the maximum total number of possible peaks in the ¹H NMR spectra of the compounds below. Label the unique types of H within the structures below as H1, H2, H3, etc. (7 pts) NOTE: keep in mind the molecule's symmetry & use the "substitution test" approach of mentally substituting, one at a time, each H for Cl, to see how many monochloro isomers you would generate. This tells you how many different types of H are present, which equals the number of possible NMR peaks (see examples in lab lecture notes).
