Question- The red fox (Vulpes vulpes) uses a chemical communication system based on scent marks in urine. Recent work has shown one component of fox urine to be a sulfide. Mass spectral analysis of the pure scent-mark component shows M+ = 116. Its IR spectrum shows an intense band at 890 cm-1. Its 1H NMR spectrum has peaks at delta 1.74 (3 H, singlet), 2.11 (3 H, singlet), 2.27 (2 H, triplet, J=4.2 Hz), 2.57 (2 H, triplet, J=4.2 Hz), and 4.73 (2H, broad). Draw its structure in the window below. [Note: (CH3)2S absorbs at delta 2.1.]
