WebA triple bond in an alkyne consists of one sigma bond and two pi bonds. As a result of the geometry of the sp hybrid orbitals, the two carbon atoms of the triple bond and the two atoms directly attached are collinear. There are two classes of alkynes— monosubstituted (terminal) and disubstituted (internal). WebAlkynes contain a C ≡C triple bond Acetylene: H-C≡C-H is the common name for ethyne, used as a torch fuel 1. Number from the end closest to the triple bond If it's a tie between the ends to two triple bonds, use branching 2. Double bonds take priority over triple bonds when they are equal distance to the end of a chain. 3. is shiraz full bodied
