Essential Chemistry for IGCSE - The Variety Of Organic Chemicals (Section 5 - No. 39)
What is the main difference in the reactivity of alkanes and alkenes?
Alkanes undergo addition reactions, while alkenes undergo substitution reactions.
Alkenes are generally more reactive due to the presence of a double bond, allowing them to undergo addition reactions.
Alkanes are more reactive because they have more hydrogen atoms.
Alkenes do not react with oxygen, while alkanes readily combust.
Explanation
Alkenes are more reactive than alkanes because the double bond provides a site for reactions, mainly addition reactions.
