The molecular formula for an unknown compound is C9H8O4.
The 1H, 13C, DEPT135, HMQC and HMBC spectra are supplied separately for the unknown compound. NMR spectra were acquired on a
500 MHz Bruker instrument using deuterated methanol (MeOD) as the NMR solvent.
Use the data to determine the structure of the unknown compound. You can then fill in the required information in the tables provided, to give full
justification for your answer. Each proton and carbon must be clearly labelled using an alphabetical system and should clearly correspond to any
inferences you list in the tables provided
