transbut2ene

transbut2ene is an organic compound with the chemical formula C4H8. It is one of the isomers of butene, meaning it has the same atoms as other butenes but arranged differently. Specifically, transbut2ene is a geometric isomer of but-2-ene, with the two methyl groups located on opposite sides of the double bond. This arrangement gives it a distinct shape and properties compared to its cis isomer.

In terms of physical properties, transbut2ene is a colorless gas at room temperature and pressure. It has a boiling point of approximately 0.9 °C and a melting point of around -105.7 °C. It is insoluble in water but soluble in many organic solvents. The molecule is nonpolar due to its symmetrical structure.

transbut2ene can be produced through various chemical reactions, including the dehydration of 2-butanol or the dehydrohalogenation of 2-halobutanes. It is often obtained as a byproduct in industrial processes like the cracking of petroleum.

Chemically, transbut2ene undergoes typical alkene reactions, such as addition reactions across the double bond. For example, it can react with halogens, hydrogen halides, and water. Due to its trans configuration, it can exhibit stereospecificity in some of these reactions.

transbut2ene finds limited direct industrial applications as a pure compound. However, it is relevant in organic synthesis and as a component in fuel mixtures. Its presence and reactivity are important considerations in understanding the behavior of hydrocarbon mixtures in various chemical processes.
