Solution
Conversion of ethene to ethane is an example of hydrogenation.
Explanation:
The conversion of ethene to ethane is a hydrogenation reaction because it involves the direct addition of hydrogen gas (H2) across the carbon-carbon double bond of the alkene. This process requires a metal catalyst like nickel, palladium, or platinum to break the unsaturated double bond and form a saturated alkane. In contrast, hydration adds water (H2O) to form an alcohol instead of an alkane.
