Alkanes and alkenes are both hydrocarbons, but they differ in chemical structure and properties. Alkanes have only single bonds between carbon atoms, making them saturated hydrocarbons (e.g., methane, ethane). In contrast, alkenes contain at least one double bond, making them unsaturated hydrocarbons (e.g., ethene, propene). Alkenes are more reactive due to the double bond, while alkanes are more stable. These differences impact their uses in fuels, plastics, and chemical reactions in various industries. For more information Visit: https://www.88tuition.com/libr....ary/alkane.-alkene%2
