Never give anything by mouth to an unconscious person. Its like a teacher waved a magic wand and did the work for me. Because of this linear shape, geometric isomerism does not occur in alkynes. 2-Butyne is an organic compound having a triple bond between two carbon atoms in the middle of the molecule. Advanced Organic Chemistry Part A: Structure and Mechanisms. 1 Butyne: Common name for 1-butyne is Ethylacetylene. If breathing is difficult, give oxygen. The two compounds are different from each other depending on the position of the triple bond. Butyne has two isomers: The triple bond in 1-butyne is terminal; it initiates at the first carbon atom. Unlike double and triple bonds, which are "locked" in their orientation, single bonds have no such restrictions. Alkynes undergo many of the same reactions as alkenes, but can react twice because of the presence of the two p -bonds in the triple bond. ed. Butyne has two isomers, which are two compounds that have the same chemical formula, but different connections between the atoms: 1-butyne and 2-butyne. Preliminary .
