this is the 1H NMR and 13C NMR of a structure. can someone
help me find out exactly the structure ?? and also detailed as
possible? & also can you identity if the structure is an
alkane, alkyl, or an aromatic compoubd with no O or N?
please thank you

In the aromatic area of the proton NMR of methyl salicylate there is a doublet at 7.81 ppm. Which aromatic proton in the structure is responsible for this resonance?
Propose a reasonable structure based on the molecular formula,
the 1H NMR, and the proton–decoupled 13C NMR data below. The
unknown compound has a molecular formula of C7H16O and * = CH2 by
DEPT.

9. If a proton gave an NMR signal at 3.2 ppm on a 60
MHz NMR, what would the chemical shift be of this proton (in ppm)
if the sample was run on 400 MHz NMR?
