Which is considered more reactive between ethane and ethene and why?
Answer and explanation
Correct answer: Ethene because it has a double bond
The governing concept is saturation and the reactivity of multiple bonds. Ethane, C2H6, is a saturated hydrocarbon containing only strong carbon–carbon single bonds. Ethene, C2H4, is unsaturated and contains a carbon–carbon double bond made of one sigma and one weaker pi bond. The pi bond can break during addition reactions, making ethene more reactive in this context. Thus option A is correct; ethane has no triple bond and both compounds are not completely inert.
