PubChem Compound Database, U.S. National Library of Medicine, Available here.2. The chemical properties of all isomers are the same; it is only the physical properties that are changing. Compounds in the alkyne group are composed only of C and H atoms bonded via single bonds, and there should be at least one triple bond between two carbon atoms. It's a highly flammable gas with four carbons and an alkyne, which is a carbon based compound with a triple bond. 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.
