I'm doing this problem and I don't know how to continue.
So far I managed to get from the 1
H NMR 6 hydrogen atoms or a multiple of 6. From the 13
C NMR 6 or 12 carbon atoms depending on symmetry.
Then with the IR spectra:
Can the 2500 cm-1
be a O-H from carboxylic acid and then 2000-1900 cm-1
the C=O from that carboxylic acid?
I'm not sure how to read the mass spectra, I get the [M]+
at 171 and [M+2]+
at 173. I'm not sure if the 172 peak is relevant or not.
Overall I guess that the compound might be some benzene acid or similar. Any help appreciated.
