What type of reaction occurs when an alkene reacts with hydrogen?

Step 1: Identify the alkene, which is a type of hydrocarbon with a double bond between carbon atoms.
Step 2: Understand that hydrogenation is a chemical reaction where hydrogen is added to the alkene.
Step 3: Recognize that during hydrogenation, the double bond in the alkene breaks.
Step 4: Know that after the double bond breaks, hydrogen atoms are added to the carbon atoms that were involved in the double bond.
Step 5: Conclude that the result of this reaction is the formation of an alkane, which is a saturated hydrocarbon with single bonds only.
