Questions & Step-by-Step Solutions
What type of reaction occurs when an alkene reacts with hydrogen in the presence of a catalyst?
Step 1: Identify the alkene, which is a type of hydrocarbon that has at least one double bond between carbon atoms.
Step 2: Introduce hydrogen gas (H2) to the reaction.
Step 3: Add a catalyst, which is a substance that speeds up the reaction without being consumed. Common catalysts for this reaction are metals like platinum, palladium, or nickel.
Step 4: The hydrogen molecules will react with the double bond in the alkene.
Step 5: The double bond will break, and hydrogen atoms will attach to the carbon atoms, converting the alkene into an alkane, which has only single bonds.
