Alkenes are more reactive than alkanes and cycloalkanes because they have a double bond. While alkanes, alkenes and cycloalkanes undergo combustion reactions with oxygen, only alkenes can participate ...

Catalysis: They are essential in catalysis, particularly in processes like hydrogenation, hydroformylation, and polymerisation. For example, Ziegler-Natta catalysts, which are organometallic compounds ...

Those with only carbon-carbon single bonds are saturated. If a compound contains at least one carbon-carbon double bond it is unsaturated and can undergo addition reactions. For example, alkenes can ...
