HINTS for PROBLEM #6

• Find the molecular weight from molecular ion in the mass spectrum
• What functional groups are present from the IR ?
• What do the peaks at 7-8 ppm in the H-nmr and at 125-145 ppm in the 13C-nmr reveal ?
• Look at the integration in the H-nmr...
• Use the above to get the molecular formula (make sure it matches the MW)
• What does "exchanges with D₂O" tell you in the H-nmr ?
