Alkene hydrogenation adds H2 across a C=C bond in the presence of a metal catalyst (e.g., Pt, Pd, Ni). This exothermic process converts unsaturated hydrocarbons to saturated ones, like converting vegetable oils (unsaturated) to margarine (partially hydrogenated). Catalyst choice and reaction conditions affect the degree of hydrogenation and potential formation of trans fats. Hydrogenation is integral to food, petrochemicals, and polymer industries.
