WebSep 25, 2024 · Alkynes can undergo reductive hydrogenation reactions similar to alkenes. With the presence of two pi bonds within alkynes, the reduction reactions can be partial to form an alkene or complete to form an alkane. Since partial reduction of an alkyne produces an alkene, the stereochemistry provided by the reaction's mechanism determines … Webketone + H2 2 ---> secondary alcohol. Reduction of Aldehydes and Ketones. Reduction: The reduction process is merely the reverse of oxidation. If two hydrogens are removed during oxidation, then two hydrogens should be added during reduction. Carbonyl compounds act as the oxidizing agent and hydrogen gas in the presence of a metal catalyst is ...
