2buten
2-Butene is an alkene with the chemical formula C4H8. It is a colorless gas at room temperature and pressure. 2-Butene exists as two geometric isomers: cis-2-butene and trans-2-butene. The difference lies in the spatial arrangement of the hydrogen atoms on the double bond. In cis-2-butene, the hydrogen atoms are on the same side of the double bond, while in trans-2-butene, they are on opposite sides. This difference in geometry leads to distinct physical properties, such as boiling points.
Both cis- and trans-2-butene are flammable and can be found in small quantities in natural gas. They
