-NMR
and H-NMR – label both unambiguously and clearly illustrate that
you understand proton and carbon environments (i.e. Draw out the
skeletal structure of the compound, label the H’s a, b, c’s and the
C’s 1, 2, 3’s. Then label all signals on the NMR with those
corresponding letters/numbers accordingly.).

1. In the H NMR of benzaldehyde, which proton is responsible for
the resonance at 10.0 ppm? In the aromatic area there are three
sets of multiplets at 7.87, 7.61 and 7.51 that integrte for 2:1:2
protons respectively. Which protons are responsible for these
multiplets?

Spectroscopy Unknown. The spectra and data provided were
obtained from a pure organic molecule. For 1 H NMR Spectra, the
integral is given in number of hydrogens (#H) or as a relative
ratio. Important coupling constants (J-values) are listed next to
the peaks for some examples. For some spectra, an inset (grey box)
is also given showing a “zoom-in” on an important part of the
spectrum.
