Chemistry - Hydrocarbon Question with Solution | TestHub

Explain the question :

To find organic products from electrolysis of potassium propanoate.

Concept :

This question is based on Kolbe electrolysis reaction.

Solution :-

Potassium propanoate (CH₃CH₂COOK) undergoes Kolbe electrolysis as follows:

At the anode (oxidation):

The propanoate ion (CH₃CH₂COO⁻) loses an electron and undergoes decarboxylation, releasing

CO₂ and forming an ethyl radical.

At the cathode (reduction):

Water is reduced, producing hydrogen gas (H₂).
