Ethane is obtained by electrolysing _:
Correct answer: B. Potassium acetate
- A. Potassium formate
- B. Potassium acetate
- C. Potassium succinate
- D. Potassium fumarate
Explanation
Ethane is obtained by electrolyzing potassium acetate in Kolbe's electrolysis. The acetate ion decomposes at the anode to form ethane, carbon dioxide, and electrons. The overall reaction is 2CH3COOK → C2H6 + 2CO2 + 2KOH. Potassium formate, succinate, and fumarate do not produce ethane through this process as they do not undergo the necessary reactions.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
