Answer» Hydrogenation– meaning, to treat withhydrogen– is achemical reactionbetween molecular hydrogen (H2) and another compound or element, usually in the presence of acatalystsuch asnickel,palladiumorplatinum. The process is commonly employed toreduceorsaturateorganic compounds. Hydrogenation typically constitutes the addition of pairs ofhydrogenatomsto a molecule, often analkene.Catalystsare required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reducesdoubleandtriplebonds inhydrocarbons. Hydrogenationis a reduction reaction which results in an addition of hydrogen (usually as H2). If an organic compound ishydrogenated, it becomes more "saturated" with hydrogen atoms. The process typically requires the use of a catalyst, sincehydrogenationonly occurs spontaneously at high temperatures Hydrogenation–meaning, to treat with hydrogen – 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. Hydrogenation–meaning, to treat with hydrogen – 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. Hydrogenation is a chemical reaction that adds hydrogen to a molecule. Hydrogenation is not thermodynamically favorable at ordinary temperatures, so a catalyst is needed. Usually this catalyst is a metal. Examples of hydrogenated products include margarine, mineral turpentine, and aniline Hydrogenation is a chemical reaction that adds hydrogen to a molecule.

Hydrogenation – meaning, to treat with hydrogen – is a chemical reaction between molecular hydrogen 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. It is used as a catalyst in addition of hydrogen. Hydrogenation refers to the treatment of substances with molecular hydrogen (H2), adding pairs of hydrogen atoms to compounds (generally unsaturated compounds). These usually require a catalyst for the reaction to occur under normal conditions of temperature and pressure. Most hydrogenation reactions use gaseous hydrogen as the hydrogen source, but alternative sources have been developed. The reverse of hydrogenation, where hydrogen is removed from the compounds, is known as dehydrogenation. Hydrogenation differs from protonation or hydride addition because in hydrogenation the products have the same charge as the reactants.
