Key Differences
Hydrogenation is a chemical process that involves the addition of hydrogen, usually to unsaturated fats or oils, making them more saturated. In contrast, reduction is a more generalized term representing any chemical reaction that involves the gain of electrons or a decrease in oxidation state. While hydrogenation specifically necessitates the presence of hydrogen, reduction can occur through various means and doesn’t necessarily involve hydrogen.
Hydrogenation is typically employed in the food industry to convert liquid oils into solid fats, thereby altering the texture and shelf-life of food products. Reduction, on the other hand, is a fundamental concept in chemistry and can be seen in myriad reactions, involving not only organic compounds but also inorganic ones. These reactions are not limited to the food industry but span across various scientific fields and applications.
In hydrogenation, the reaction specifically involves the use of hydrogen gas, and typically a catalyst like nickel is used to facilitate the reaction. Reduction, being a broader term, can involve various reagents and can be achieved by different methods, like the removal of oxygen, addition of hydrogen, or addition of electrons, depending on the context of the chemical equation.
Hydrogenation primarily focuses on modifying the physical properties of substances, particularly in the context of food production. However, reduction reactions encompass a variety of chemical processes and applications, such as the reduction of metal ores to obtain pure metals. Both processes are critical in their respective fields, but they have different scopes and applications.
While hydrogenation is a subtype of reduction, not all reduction reactions are hydrogenation reactions. This distinction arises because reduction reactions can involve different elements and compounds, reflecting the diversity and versatility of reduction reactions in chemistry, compared to the more specialized and focused nature of hydrogenation processes.

Sine
In mathematics, the sine is a trigonometric function of an angle.
