Characterized by a cyclic cloud of delocalized pi electrons, they are relatively unreactive despite being highly unsaturated.
These compounds are substituted through aluminum-trichloride-catalyzed alkylation and acylation reactions. Cyclooctatetraene is not one of these compounds, because it is tub-shaped rather than planar. Characterized by sp2 ("s p two") hybridization and a small carbon-to-hydrogen ratio, these compounds must have a number of pi electrons that is 2 more than a multiple of 4, according to Hückel's rule. Characterized by a cyclic cloud of delocalized pi electrons, they are relatively unreactive despite being highly unsaturated. For 10 points, name these compounds, exemplified by pyridine and benzene, whose name suggests a pleasant odor.
