Hexene

Hexene ( stress on the second syllable) are chemical compounds from the group of alkenes with the molecular formula C6H12. The root word hex has six carbon atoms, the suffix s indicates the double bond between two carbon atoms. There are various isomers differing in the position of the double bond and the presence or the position of a branch in the carbon chain. The compound used in the industry is most often 1-hexene, which is used, for example, as a comonomer in the production of polyethene.
