Given this IR Spectra of an unknown compound, how do I
determine the structure of what I have?
I think I have some sort of ketone? Possibly a methyl
ketone.
Attached is also the H-NMR. Please help determine structure of
unknown.
the
only other information i have is that it has a low molecular weight
and is neutral
