- The double bond present in alkenes, such as ethylene, makes them much more reactive than their corresponding alkanes.
- Many substances react with alkenes through breaking open the double bond into two single bonds, this being an example of an addition reaction.
- Addition Reaction: A reaction in which two or more molecules are reacted together to form a single molecule.
