    shweta, alkyl halides can't directly reduced to alkane by H2/pd rather alkyl halide first undegoes dehydrohalogenation and forms alkene then alkene adds with H2(hydrogenation react...

    sir how it first undergoes dehydrohalogenation ..as . there is no any strong base
  • Priyanshu kumar
    shweta addition of Hydrogen(H2) to alkene ,reaction is called hydrogenation and this reaction is adsorption reaction....as the metal catalysts used here is Ni,Pd and Pt which provi...

    and H2 doesn't adds to alkyl halide
  • Dinesh khalmaniya
    yes, shweta. Alkyl halides can also be reduced catalytically to alkane by H2/Pd or LiAIH4 or by H2/Ni. The yields are generally high and the hydrocarbons formed are pure. reduction...

    sir In presence of zn /hcl also this is only the mechanism
  • Priyanshu kumar
    The reaction is heterogeneous catalysis or surface catalysis as metal catalyst provide a surface for binding..
