An unknown compound produces an 1H NMR spectrum with only three signals: 1.8, 2.8, 7.5 (broad) ppm, all singlets that integrate in a 6:3:1 ratio, respectively. The 13C NMR spectrum shows 4 signals. Both spectra are provided below. The mass spectrum shows a molecular ion region with the following peaks: m/z 135 (100%), 136 (5.9%), 137 (33%). Determine the number of carbons, molecular formula, and propose a structure. Assign all 1H and 13C NMR signals to specific chemical environments or specific hydrogens in your structure.

NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.
