Catalytic hydrogenation of an alkene is an important reduction reaction in Organic Chemistry-II, where an alkene is converted into the corresponding alkane by addition of hydrogen in the presence of a metal catalyst such as Pt, Pd, Ni, or Rh. The reaction proceeds through adsorption, activation, addition and desorption steps, occurring on the catalyst surface, and follows syn addition of hydrogen across the double bond. The mechanism begins when molecular hydrogen gets adsorbed on the metal surface and undergoes dissociation into two hydrogen atoms due
