Detailed Solution
Download Solution PDFThe correct answer is CH4 (Methane).
- Kolbe's electrolytic method is suitable for the preparation of symmetrical alkanes that alkanes contain an even number of carbons. So methane has only one carbon.
- Hence Methane cannot be prepared by Kolbe's electrolytic method.
Additional Information
Kolbe's electrolysis method:
- It is a chemical process used to synthesize alkanes from carboxylic acids through the electrolysis of their salts in an aqueous solution.
- The method is named after German chemist Hermann Kolbe, who discovered it in 1849.
- The process involves passing an electric current through a solution of the sodium or potassium salt of the carboxylic acid, which causes the carboxylate ions to be reduced at the cathode and oxidized at the anode.
- The reduction of the carboxylate ions produces alkyl radicals, which then combine to form the desired alkane.
