Alkanes and alkenes are hydrocarbons with different structures and properties. Alkanes are saturated hydrocarbons with single bonds, making them less reactive. Examples include methane and propane. In contrast, alkenes are unsaturated hydrocarbons with at least one double bond, making them more reactive. Ethene and propene are common alkenes. The main difference between alkanes and alkenes lies in their chemical bonds, which affect their reactions, such as combustion and addition reactions in organic chemistry.
