Questions & Step-by-Step Solutions

Which reagent is commonly used to convert alkynes to alkenes?
  • Step 1: Identify the starting material, which is an alkyne (a molecule with a triple bond).
  • Step 2: Choose the reagent needed for the reaction, which is hydrogen gas (H2).
  • Step 3: Select a catalyst to help the reaction occur more easily; common catalysts include palladium (Pd), platinum (Pt), or nickel (Ni).
  • Step 4: Combine the alkyne, hydrogen gas, and the catalyst in a suitable reaction environment.
  • Step 5: Allow the reaction to proceed, which will convert the alkyne into an alkene (a molecule with a double bond).
