Question

Potassium salt of which acid will be needed for the preparation of ehane in Kolbes electrolysis? Write chemical equation for the reaction.​

Answer 1

Answer:

CH3−CH2−COO−Na+⟶electrolysisAtanodeCH3−CH3+AtcathodeCO2.

Answer 2

Hi! Sodium or potassium salt of a dicarboxylic acid on electrolysis gives an alkene. An alkene is generated when an aqueous solution of sodium or potassium salt of a dibasic acid (with adjacent carboyxlic groups) is electrolyzed. The electrolysis of sodium succinate gives ethene.
