Which of the following is a characteristic reaction of alkenes?
Correct Answer: Hydrogenation
Step 1: Understand what alkenes are. Alkenes are hydrocarbons that contain at least one double bond between carbon atoms.
Step 2: Learn about hydrogenation. Hydrogenation is a chemical reaction where hydrogen is added to a compound.
Step 3: Identify the catalyst. A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.
Step 4: Recognize that during hydrogenation, alkenes react with hydrogen gas (H2) in the presence of a catalyst, usually nickel, palladium, or platinum.
Step 5: Conclude that hydrogenation is a characteristic reaction of alkenes because it converts the double bond into a single bond, resulting in a saturated hydrocarbon.
