Ethyl iodide and n-propyl iodide are allowed to undergo the Wurtz reaction. The alkane which will not be obtained in this reaction is:

Correct answer: B. Propane

  • A. Butane
  • B. Propane
  • C. Pentane
  • D. Hexane

Explanation

In the Wurtz reaction, two alkyl halides react with sodium to form a higher alkane. Ethyl iodide (C2H5I) + n-propyl iodide (C3H7I) can give butane (C2+C2), pentane (C2+C3), and hexane (C3+C3). Propane (C3H8) cannot be formed because no combination of these two halides produces it.

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.
