WebThe meaning of KOLBE REACTION is the synthesis of a hydrocarbon (as ethane) by the electrolysis of a salt (as sodium acetate). WebSolution. Verified by Toppr. Decarboxylation is a chemical reaction that removes carboxyl group & releases CO 2. . . In this process release of carbon from the end of a carbon chain occurs (i.e. knocking off carbon atom). In the given reaction, decarboxylation causes the formation of methane. Example: CH 3− C ∣∣O−ONa+NaOH CaO CH 4+Na 2CO 3.
