The FTIR spectrum indicates the presence of functional groups, with a broad peak at 3000 cm\u207b\u00b9 suggesting O-H or N-H groups, and strong peaks at 1700 cm\u207b\u00b9 and 1650 cm\u207b\u00b9 indicating carbonyl (C=O) and possibly conjugated carbonyls. The 1H NMR spectrum shows peaks for vinyl hydrogens, suggesting the presence of alkenes. The mass spectrum fragment at m/z = 45 indicates a possible loss of a small fragment, consistent with the presence of a carboxylic acid or ester. Based on this analysis, the correct chemical formula is determined to be C6H10O2."}
