WebBecause of the lack of rotation of C=C double bonds these two molecules are different. But they have the same formula so they are isomers. And the atoms are arranged in the same order with the only difference being the spatial arrangement of the bonds - hence Stereo -isomers. So they'll need different names despite both being But-2-ene. Web21 nov. 2024 · Alkenes are unsaturated aliphatic hydrocarbons having one or more carbon-carbon double bonds i.e. C=C. Since alkenes form oily products with halogens, they are called olefins. They contain two hydrogen atoms less than the corresponding alkanes. The general formula for alkenes is C n H 2n, Where n = number of carbon atoms.
