Hydrogenation vs. Reduction: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 28, 2023
Hydrogenation is adding hydrogen to a molecule, while reduction is a broader chemical reaction involving the gain of electrons or decrease in oxidation state.

Key Differences

Hydrogenation specifically involves the addition of hydrogen to another molecule, often used to saturate organic compounds. Reduction, however, is a more general term in chemistry that signifies the gain of electrons by a substance, which can involve but is not limited to hydrogen addition.

Hydrogenation is a type of reduction, it's exclusively focused on the incorporation of hydrogen atoms into a molecule. In contrast, reduction can encompass a wider range of processes, including the removal of oxygen, gain of electrons, or increase in hydrogen, but not exclusively hydrogen.

In the context of organic chemistry, hydrogenation is often associated with the conversion of unsaturated compounds to saturated ones by adding hydrogen. Reduction, in a broader sense, could mean any reaction where a molecule, atom, or ion experiences a decrease in its oxidation state.

Hydrogenation is a specific chemical reaction, often catalyzed by metals like palladium or nickel. Reduction, on the other hand, can occur in various ways, such as by chemical reagents, electrochemically, or biologically, and is not limited to the addition of hydrogen.
