However, there are no geometric isomers with alkynes because there is only one other group bonded to the carbon atoms that are involved in the triple bond. Alkenes can also demonstrate structural isomerism. [2] It is one of the isomers of butene (butylene). Butyne is a colorless gas that's very flammable and is a compound that can easily create a loud boom. Butene, hexene, propene are some common examples for alkenes. One of the interesting aspects of organic chemistry is that it is three-dimensional. The {eq}C-C {/eq} covalent bonds are formed when two carbon atoms share one of their unpaired electrons with one another. Richard J. Lewis, Sr., Hawley's Condensed Some of the.
