Hydrogenation of alkenes and alkynes takes place in presence of certain catalysts. In sabatier-Senderen's reaction, the addition of hydrongen taken place in presence of nickel catalyst. Controlled hydrogenation of alkyne in presence of Lindlar's catalyst gives cis-alkene. Non terminal alkynes are reduced by Na or Li metal dissolved in liquid NH_(3). In this reaction trans alkenes are formed. Q. The product of the following reaction is
