Alkene plus hydrogen with the presence of metal catalysts produces alkane
Hydrogenation of Alkene
Catalyst used in hydrogenation of alkene
Ni, Pt or Pd poisoned
Alkyl halide reacted with magnesium with presence of dry ether produces alkyl magnesium halide or known as Grignard reagent. Grignard reagent will be hydrolyzed with acidic hydrogens or water which will produce an alkane (R-H) and magnesium hydroxide X (Mg(OH)X).
Hydrolysis of Grignard Reagent
Two molecules of alkyl halide will be reacted with two molecules of metallic sodium thus producing an alkane and two sodium halide (NaX).
Wurtz Reaction
An alkane will be reacted with chlorine/bromine with the presence of light/heat or organic peroxide which will produce an alkyl halide and hydrogen halide.
Halogenation of Alkane
An alcohol will be heated with the presence of strong acids such as sulfuric acid, phosphoric acid or p-toluene sulfonic acid which will produce an alkene.
Dehydration of Alcohol
An alkyl halide will be reacted with a base (KOH) and will produce an alkene, potassium halide and water.
Dehydrohalogenation of alkyl halide
A vicinal dihalide will be reacted with zinc dust and will produce an alkene and zinc halide (ZnX2).
