Write an account on the following reactions involving formation of alkane.
Kolbe's Electrolytic method.

Explanation

Kolbe's Electrolytic method :
When sodium or potassium salt of carboxylic acid is electrolyzed, a higher alkane is formed. The decarboxylative dimerization of two carboxylic acid occurs. This method is suitable for preparing symmetrical alkanes `(R-R)`.
