How many aromatic compounds are there
WebPolycyclic aromatic hydrocarbons (PAHs) are a large group of diverse organic compounds that contain two or more fused aromatic rings ranging from the two-ring naphthalene and naphthalene derivates to complex ring structures containing up to 10 rings. PAHs with up to six fused aromatic rings are often known as ‘small’ PAHs, whereas those containing more … Webaromatic compound, any of a large class of unsaturated chemical compounds characterized by one or more planar rings of atoms joined by covalent bonds of two different kinds. The …
