Hydrogenation of alkenes and alkynes takes place in presence of certain catalysts. In Sabatier Senderen's reaction, the. addition ·of hydrogen takes·· place in presence of Raney nickel· catalyst. Platinum and palladium can also be used as catalyst in these reactions. These are heterogeneous catalyst and used in. finely. divided state. Experimentally, it is observed that less. crowded alkenes adsorb H2 with faster rate. Controlled hydrogeneration of alkyne in presence of Lindlar's catalyst
yields cis product i.e., 'cis' alkene. Thus, in presence of Lindlar's catalyst 'syn' addition takes place. The relative rate of hydrogenation follows the order:
Non-terminal alkynes an reduce4 in presence of Na or Li metal dissolved in liquid ammonia. In this reaction, anti-addition of hydrogen results into the
trans-product. .
The product of the following reaction is:
