Which one of the following reactions is used to produce symmetrical alkanes from alkyl halides?
Correct answer: D. Wurtz reaction
- A. Wurtz-Fittig reaction
- B. Kolbe's electrolysis
- C. Reduction of alkyl halide
- D. Wurtz reaction
Explanation
The correct answer is D (Wurtz reaction). The Wurtz reaction is commonly used to produce symmetrical alkanes from alkyl halides. In this reaction, alkyl halides react with sodium metal in the presence of a suitable solvent (usually ether) to form a new carbon-carbon bond.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
