Catalytic Hydrogenation of Ethylene

C2H4 + H2 → C2H6

概述

Ethylene is reduced to ethane by addition of hydrogen across the double bond, catalyzed by a transition metal surface. Both hydrogen atoms add to the same face of the alkene (syn addition). The metal catalyst adsorbs both H₂ and the alkene, weakening bonds and facilitating the reaction.
