Pyrene
Pyrene
Pyrene (pronounced: /paɪˈriːn/) is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. The chemical formula is C16H10. This yellow crystalline solid is the smallest peri-fused PAH (one where the rings are fused through more than one face). Pyrene forms during incomplete combustion of organic compounds.
Etymology
The term "Pyrene" is derived from the Greek word "πυρ" (pyr), meaning "fire", due to its discovery in coal tar, a byproduct of the combustion of coal.

- Benzene ring: A hexagonal arrangement of six carbon atoms, with alternating single and double bonds, and with a hydrogen atom bonded to each carbon atom.
- Coal tar: A thick, black, viscous liquid produced during the destructive distillation of coal. It is a complex mixture of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds.
- Combustion: A high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.
