Ethylene’s Bonding and Products

Production of Materials‎ > ‎1. Fossil Fuel Products‎ >

Identify that ethylene, because of the high reactivity of its double bond, is readily transformed into many useful products

  • The double bond present in alkenes, such as ethylene, makes them much more reactive than their corresponding alkanes.
  • Many substances react with alkenes through breaking open the double bond into two single bonds, this being an example of an addition reaction.
  • Addition Reaction: A reaction in which two or more molecules are reacted together to form a single molecule.
