Which of the following reactions is an example of hydrogenation? (2023)
Step 1: Understand what hydrogenation means. It is a chemical reaction where hydrogen (H2) is added to a compound.
Step 2: Identify the type of compounds involved. Hydrogenation typically occurs with unsaturated hydrocarbons, which have double or triple bonds.
Step 3: Look for an example of hydrogenation. A common example is the reaction of ethene (C2H4), which has a double bond, reacting with hydrogen to form ethane (C2H6), which has only single bonds.
Step 4: Confirm that the reaction involves adding hydrogen to the unsaturated compound, resulting in a saturated compound.
