Answer» Explanation:Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another COMPOUND or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation TYPICALLY constitutes the addition of pairs of hydrogen atoms to a MOLECULE, often an alkene. Catalysts are required for the reaction to be USABLE; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and TRIPLE bonds in hydrocarbons.[1] |
