aryyliryhmiä
Aryyliryhmiä, often translated as aryl groups, are a class of organic chemical substituents derived from aromatic hydrocarbons. In essence, an aryl group is an aromatic ring system that has had one or more hydrogen atoms removed, allowing it to bond to another part of a molecule. The most common and simplest aryl group is the phenyl group, which is derived from benzene by removing a hydrogen atom. Its chemical formula is C6H5-. Other examples include naphthyl (derived from naphthalene) and anthracenyl (derived from anthracene).
Aryl groups are characterized by their planar structure and the delocalized pi electron system within the
