13hexadiene

1,3-hexadiene is an organic compound with the chemical formula C6H10. It is a diene, meaning it contains two carbon-carbon double bonds. The "1,3" in its name indicates the positions of these double bonds within the six-carbon chain. Specifically, the double bonds are located between the first and second carbon atoms, and between the third and fourth carbon atoms. It exists as cis and trans isomers for the double bond at the 3,4 position, leading to 1,3-hexadiene (1,3-cis-hexadiene) and 1,3-trans-hexadiene.

1,3-hexadiene is a colorless liquid at room temperature and pressure. Like other alkenes, it is relatively nonpolar and is soluble in organic solvents but poorly soluble in water. Its reactivity is primarily associated with the conjugated double bond system. Conjugated dienes are known to undergo various addition reactions, including Diels-Alder reactions, where they act as dienes and react with dienophiles to form cyclic compounds.

This compound can be synthesized through various organic reactions, often involving dehydration or dehydrohalogenation of appropriate precursors. It can also be a byproduct of certain industrial processes, such as the cracking of petroleum. 1,3-hexadiene is used in research as a building block in organic synthesis, particularly for creating more complex molecules through its characteristic reactivity. Its potential applications are explored in areas such as polymer chemistry and the synthesis of specialty chemicals.
