Question

What is hydrogenation?Give it’s one example.

Answer 1

Hydrogenation – 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. 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.


An example of an alkene addition reaction is a process called hydrogenation.In a hydrogenation reaction, two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane. ... The metal catalyst also absorbs the alkene onto its surface.

Answer 2

Hydrogenation Is a chemical reaction between hydrogen(h2) and a compound or element in presence of a catalyst.
Example: conversation of ethene to ethane.
