Questions & Step-by-Step Solutions

Which reaction is used to convert alkenes to alkanes?
  • Step 1: Identify the starting material, which is an alkene. Alkenes are hydrocarbons that have at least one double bond between carbon atoms.
  • Step 2: Understand that to convert an alkene to an alkane, you need to add hydrogen atoms.
  • Step 3: The process of adding hydrogen to the alkene is called hydrogenation.
  • Step 4: During hydrogenation, a catalyst (often nickel, platinum, or palladium) is usually used to speed up the reaction.
  • Step 5: The double bond in the alkene breaks, and hydrogen atoms are added to the carbon atoms, resulting in an alkane, which has only single bonds.
