Sometimes a number between hyphens is inserted before it to state which atoms the triple bond is between.
Other functional groups containing a triple bond are cyanides and isocyanides.
Nevertheless, strained alkyne is a better description of the triple bond nature of ortho-benzyne than biradical (larger singlet-triplet gap and alkyne-like reactivity).
Besides the single bond, a covalent bond can be either a double bond or a triple bond.
It is the synthetic and reactive equivalent of an acyl carbocation, but the actual structure has the oxygen and carbon linked by a triple bond.
The most common triple bond, that between two carbon atoms, can be found in alkynes.
The molecule resembles carbon monoxide with a triple bond between carbon and sulfur.
In these compounds the boron and oxygen form a triple bond prone to cyclotrimerization to boroxines.
