Questions & Step-by-Step Solutions

What is the main product when propene is reacted with hydrogen in the presence of a catalyst?
Correct Answer: Propane
  • Step 1: Identify the starting material, which is propene (C3H6).
  • Step 2: Understand that hydrogenation is a chemical reaction where hydrogen (H2) is added to a compound.
  • Step 3: Recognize that a catalyst is used to speed up the reaction without being consumed.
  • Step 4: When propene reacts with hydrogen in the presence of a catalyst, the double bond in propene breaks.
  • Step 5: The hydrogen atoms add to the carbon atoms that were involved in the double bond.
  • Step 6: This reaction converts propene (C3H6) into propane (C3H8), which is the main product.
