Molecular geometry of ethyne.

Alkynes. An alkyne is a hydrocarbon with one or more carbon-carbon triple covalent bonds. The simplest alkyne consists of two carbon atoms and is called ethyne (common name: acetylene). The ethyne molecule is linear, with sp s p hybridization for each carbon atom. The general formula of alkynes with one triple bond is CnH2n−2 C n H 2 n − 2.Bonding in Ethane. In the ethane molecule, the bonding picture according to valence orbital theory is very similar to that of methane.
