Asked in UHS MDCAT 2010 2010Moderate

Symmetrical alkanes can be produced by:

Correct answer: D. Kolbe's Electrolytic Reaction

  • A. Sabatier Sender's Reaction
  • B. Hydrogenolysis Reaction
  • C. Reduction Reaction
  • D. Kolbe's Electrolytic Reaction

Explanation

A is incorrect as Sabatier-Sender's reaction is the reaction in which preparation of ethane is done by the catalytic hydrogenation of ethene, it does not produce symmetrical alkanes.B is incorrect as Hydrogenolysis is a chemical reaction whereby a carbon-carbon or carbon-heteroatom single bond is cleaved or undergoes lysis (breakdown) by hydrogen, it does not produce symmetrical alkanes.C is incorrect as the reduction reaction is when a species gain electrons.D is correct as Kolbe's electrolysis method is a general method of preparation of substituted hydrocarbons from the substituted carboxylic acids by the use of the electric discharge method where carbon dioxide gas is released, it produces symmetrical alkanes

About Alkanes

Alkanes are saturated hydrocarbons containing only carbon-carbon and carbon-hydrogen single bonds, with the general formula CnH2n+2 for open chains. Their structure, isomerism, IUPAC nomenclature, physical properties, combustion, free-radical halogenation and conformations are covered, including the difference between substitution in alkanes and addition in unsaturated hydrocarbons.
