Question

Which of the following would not form upon electrolysis of aqueous solution of potassium propanoate?

• A. Butane
• B. Ethyl ethanoate
• C. Ethyl propanoate
• D. Ethene

Answer 1

Answer: (B)

Ethyl ethanoate

Answer 2

$C{{H}_{3}}C{{H}_{2}}COOK\xrightarrow[{}]{Electrolysis}\underset{I}{\mathop{C{{H}_{3}}C{{H}_{2}}CO{{O}^{\bullet }}}}\,$ $\xrightarrow[{}]{{}}\underset{II}{\mathop{CH_{3}^{\bullet }C{{H}_{2}}}}\,$ $2II\xrightarrow[{}]{{}}$ Butane; $I+II\xrightarrow[{}]{{}}$ ethyl propanoate $II\xrightarrow[{}]{disproportionation}$ ethene + ethane.
