Why does hydrogen react with oil?

Answer 1

First off, reactions generally favor the more stable product. Hydrogen is a reactive gas and will try to react with other substances in order for it to form a more stable product. In the case of oils, hydrogen generally will be reacting with a carbon-carbon double bond. A double bond in carbon is more reactive than a single carbon-carbon bond and two carbon - hydrogen bonds, which is what forms during an oil and hydrogen reaction. This is what is known as a hydrogenated oil, which is less prone to spoiling than a non hydrogenated oil as it is a less reactive. To go more indepth, you would need some knowledge of organic chemistry and possibly physical chemistry.

Answer 2

Hydrogen reacts with oil through a process called hydrogenation, where hydrogen molecules are added to the carbon-carbon double bonds present in unsaturated fats or oils. This reaction can increase the stability and shelf life of the oil and convert liquid oils into solid fats, such as margarine.
