Spectra led to your assignment of the functional groups
assign all of the peaks in the NMR Spectrum to the protons in
your molecule (would you please explain how you assigned number of
hydrogen to each peak in the H-NMR. THANK YOU)

Provide the correct structure for your unknown based on the
spectroscopic data provided. Provide the correct name for your
compound. Either the IUPAC name, or a commonly accepted name (i.e.,
ethyl acetate in place of ethyl ethanoate) will be accepted.IR
spectrum: Assign as many peaks as possible. In particular, you
should assign peaks that were important in making your structural
interpretation (i.e. functional group peaks such as OH, C=O, N-H,
etc.).

Exists as an equilibrium mixture of diketone and two enol forms.
Both the diketonr and enol forms can be seen in the provide IR
spectrum although the two different enols cannot be distinguished.
The IR spectra of both enols is essentially identical and so do not
be concerned with distinguishing the enols, just assign peaks to a
"generic" enol.
