Question

Once the student was able to recover what she hopes is her acidic compound, she analyzed the compound with GC/MS, UV-VIS, IR, 1H NMH and 13C NMR.  She now needs help analyzing her spectral data to determine if the compound she recovered was in fact her acidic compound.

Additional Information:

Molecular Formula:                 C7H6O2

Mass Spectrum Data:                                                              UV-VIS Data:

Molecular Ion (M+)                 122 m/z                                    lmax 241 nm

Fragment                                 105  m/z (base peak)                (log10 e 4.1)

Fragment                                 77 m/z
