Question

What is Kolbe’s electrolytic method?

Answer

Kolbe's electrolytic method is a process used for the preparation of Alkane. In it alkanes are obtained by the electrolysis of sodium salt of carboxylic acid. e.g., 2CH₃COONA + 2CH₃COO^- + 2Na⁺ At anode 2CH₃COO → CH₃ + 2CO₂ + 2e^- At cathode 2Na⁺ + 2e^- → 2Na 2Na + 2H₂O → 2NaOH + H₂ ↑
