Question

On electrolysis of potassium succinate solution, the hydrocarbon obtained is:

• A. Ethene
• B. Ethane
• C. Ethyne
• D. All of these

Answer 1

The correct option is A Ethene

Accornding to the Kolbe reaction where in this reaction the formation of decarboxylative dimerisation of two carboxylic acids. Where overall general reaction of Kolbe reaction is:

$2R-CO{O}^{-}$ $\to$ $R-R$ +$2C{O}_2$ +2e
In dicarboxylates the intramolecular bonding produces alkene. Potassium succinate results in formation of ethene by Kolbe electrolysis.
