What type of reaction occurs when alkenes undergo hydrogenation?
Correct Answer: Addition reaction
Step 1: Identify the starting material, which is an alkene. Alkenes have a double bond between two carbon atoms.
Step 2: Understand that hydrogenation is a chemical reaction where hydrogen (H2) is added to the alkene.
Step 3: Recognize that during hydrogenation, the double bond in the alkene breaks and two hydrogen atoms are added to the carbon atoms that were previously double-bonded.
Step 4: Conclude that the result of this reaction is an alkane, which has only single bonds between carbon atoms.
