hydrogenation of benzene reaction mechanism

12 g of an alkyne are mixed with 11.2 L H, in STP in the presence of Ni and the mixture is heated. At the end of the reaction, a gaseous mixture of two hydrocarbons is formed which cannot react with Na. Half of the mixture of the two hydrocarbons can decolorize 250 mL of Br solution, 0.2 M in CCl solvent. Determine: a. the structural formula of hydrocarbon b. the qualitative and quantitative (in mol) composition of the gas mixture resulting from the hydrogenation reaction. Given Ar: C-12 H-1
