Question

Aqueous solution containing both sodium acetate and sodium propionate on electrolysis yields? Answer is all- ethane, propane and butane. Pls show the reaction and under which method of preparation of alkane it comes?

Answer 1

The electrolysis of salts of Carboxylic acids which finally produces alkanes is called Kolbe de-Carboxylation reaction. During this reaction Carbon dioxide is released at anode along with formation of alkanes. 2R-COONa (on Electrolysis) → R - R + 2CO2 + H2 + NaOHExample: Sodium acetate on electrolysis produces ethane. 2CH3COONa → CH3 - CH3+ 2CO2 + H2 + NaOH

Answer 2

Answer:

All the below mentioned reactions take place while this process of electrplysis and hence we obtain all ethane,propane and butane
