Aqueous solution of sodium salt of propanoic acid on electrolysis givesn – Hexanen – ButanePropanen – Pentane

The electrolysis of an aqueous solution of sodium salt of propanoic acid primarily leads to the formation of alkanes through various reactions. Here's a breakdown of what happens during the process:

1. Electrolysis Process: During electrolysis, the sodium propanoate dissociates into sodium ions and propanoate ions. The propanoate ions can undergo various reactions at the electrodes.

2. Formation of Alkanes: The electrolysis results in the cleavage of the propanoate ion, leading to the formation of alkanes as byproducts. The specific alkanes mentioned (hexane, butane, propan, pentane, etc.) can be formed depending on the reaction conditions and the number of propanoate units that react.

3. Reactions:

   • The generation of larger alkanes suggests chain growth through various mechanisms including decarboxylation and coupling reactions.
   • The direct coupling of shorter-chain radicals can yield longer-chain alkanes.

From these points, we can summarize the key transformations and products:

• Hexane: Formed from the combination of smaller alkyl groups.
• Butane: Another product of smaller chain coupling.
• Propane: The simplest product from the initial propanoate.
• Pentane: Often arises from coupling reactions involving propyl radicals.

Final Answer

The electrolysis of an aqueous solution of sodium salt of propanoic acid yields several alkanes, primarily hexane, butane, propane, and pentane, through various coupling and radical mechanisms.
