In chemistry, an aryne's an uncharged reactive intermediate derived from an aromatic system by removal of two ortho substituents, leaving two orbitals with two electrons distributed between them.. In analogy with carbenes and nitrenes, an aryne has a singlet state and a triplet state. The simplest aryne, C6H4 (labeled 1 in the diagram to the right),'s sometimes called benzyne. However, this name's open for criticism because it implies a triple bond which would be a special case of triple bonds,… (More on Aryne)
