Meaning
Butene is a gaseous (at room temperature) hydrocarbon with chemical formula C4H8.
About Butene
- Butene is hydrocarbon because it contains only Hydrogen and Carbon atoms.
- Butene can be oxidised to produce Carbon Dioxide and Water.
- Butene + Oxygen → Carbon Dioxide + Water

- Butene is hydrocarbon because it contains only Hydrogen and Carbon atoms.
- Butene has a double bond between two Carbon atoms.
- Butene is described as 'unsaturated' due to the double bond as it is not completely 'saturated' by Hydrogen atoms like Butane.
- Butene can be oxidised to produce Carbon Dioxide and Water.
- Butene + Oxygen → Carbon Dioxide + Water
- <chem>C4H8 + 6O2 -> 4CO2 + 4H2O</chem>
