Solution
The correct option is B Ethyne
Answer
(B) Ethyne
Kolbe’s electrolytic process is used to prepare alkanes.
Kolbe’s electrolytic process
In this process, the alkane is produced through electrolysis of sodium or potassium salt of carboxylic acid. In this reaction, two molecules of sodium acetate and two molecules of water, on electrolysis, produce one molecule of ethane, two molecules of carbon dioxide, one molecule of hydrogen and two molecules of sodium hydroxide.
2CH3COO Na + 2H2O →CH3 – CH3 + 2CO2 + H2 + 2NaOH
