Methane can be converted into ethane by the reactions
Options
- Achlorination followed by the reaction with alcoholic KOH
- Bchlorination followed by the reaction with aqueous KOH
- Cchlorination followed by Wurtz reaction
- Dchlorination followed by decarboxylation
Correct answer
C. chlorination followed by Wurtz reaction
Step-by-step solution
The chlorination of methane is carried out by treating it with chlorine in presence of ultraviolet light or by heating the reaction mixture to 520-670 ~K . methane CH ₄ + Cl ₂ hv or methyl chloride CH ₃ Cl + HCl This methyl chloride react with metallic Na in presence of dry ether to form symmetrical alkane the number of carbon atoms (ethane). This reaction is called Wurtz reaction.
