¹H NMR: δ 8.60 (2H, m), 7.65 (1H, tt, J = 8.0, 1.6 Hz), and 7.26 (2H, m)

¹³C NMR: 148.8, 134.9, and 122.8 ppm.

The degree of unsaturation is 4. The ¹³C spectrum reveals three different types of carbon and the ¹H NMR spectrum displays three groups of aromatic hydrogens. These data suggest that each carbon bears one hydrogen atom and that that there are to C-H arrangements that are the same. Pyridine appears to satisfy this structure. The single hydrogen at δ 7.65 is a triplet of triplets coupled to the blue ortho hydrogens (J = 8.0 Hz) and to the red meta hydrogens (J = 1.6 Hz). Return to Menu.
