: [[Ethene]] + [[Oxygen]] → [[Carbon]] + [[Carbon Monoxide]] + [[Water]]
: <chem>2C2H4 + 3O2 -> 2C + 2CO + 4H2O</chem>
====Reaction with Halogens====
When [[halogen]]s are added to [[alkene]]s the [[Double Bond|double bond]] in the [[alkene]]s breaks and the [[halogen]] [[bond]] in its place.
: [[Ethene]] + [[Chlorine]] → [[Dichloroethane]]
: <chem>C2H4 + Cl2 -> C2H4Cl2</chem>
: [[Propene]] + [[Bromine]] → [[Dibromopropane]]
: <chem>C3H6 + Br2 -> C3H6Br2</chem>
: [[Butene]] + [[Iodine]] → [[Diiodobutane]]
: <chem>C4H8 + I2 -> C4H8I2</chem>
====Reaction with Hydrogen====
[[Alkene]]s can be [[Saturated Hydrocarbon|saturated]] with extra [[Hydrogen]] using a [[catalyst]].
