All the bonds in butyne are covalent bonds, such bonds are formed when two atoms share at least one of their valence electrons with one another. Molecules can differ in the way the atoms are arranged - the same combination of atoms can be assembled in more than one way. The terminal alkyl groups of 2-butyne provide electrons to sp-hybridized carbon, thus stabilizing the alkyene while decreasing the heat of hydrogenation. For example, 1-butene has a double bond followed by two single bonds while 2-butene has a single bond, then a double bond, then a single bond. In both molecules, the bonding order of the atoms is the same.
