aromatískum
Aromatiskum is a term derived from the Greek word "aroma," meaning "fragrant." In chemistry, it refers to a class of cyclic organic compounds that exhibit a special stability due to a delocalized pi electron system within their ring structure. The most fundamental example of an aromatic compound is benzene, a six-carbon ring with alternating double bonds. This arrangement, however, is not accurately represented by simple resonance structures. Instead, the pi electrons are spread evenly around the entire ring, creating a stable, lower-energy state.
The defining characteristic of aromaticity is often described by Hückel's rule, which states that an aromatic
