problem

The 1H NMR spectrum of unknown molecule X is in <INCHI>InChI=1S/CHCl3/c2-1(3)4/h1H/i1D</INCHI>, <SMILES>

2H

C(Cl)(Cl)Cl</SMILES, <IUPAC>trichloro(deuterio)methane</IUPAC> has an exchangeable singlet for 1H at 12.0 ppm, a doublet for 2H at 7.73 ppm, a doublet for 2H at 7.46 ppm, a doublet for 1H at 7.19 ppm, and a doublet for 1H at 6.25 ppm. X has the chemical formula C9H7NO4. Identify X. Think step by step and solve the problem below. At the end of your response, write your final answer on a new line starting with “FINAL ANSWER”. It should be an answer to the question such as providing a number, mathematical expression, formula, or entity name, without any extra commentary or providing multiple answer attempts.
