1,3-Hexadiene is a colorless liquid hydrocarbon with the chemical formula C6H10. It belongs to the class of compounds known as alkenes, which are characterized by having at least one carbon-carbon double bond. Specifically, 1,3-hexadiene contains two double bonds located at the first and third carbon atoms in its six-carbon chain. This compound is used in various industrial applications, including the production of synthetic rubber and as a building block in organic synthesis. Due to its unsaturated nature, 1,3-hexadiene can undergo reactions typical of alkenes, such as polymerization and addition reactions, making it valuable in chemical manufacturing.
