Correct Answer: Hermann Kolbe

Solution : The correct option is Hermann Kolbe .

The German chemist who used the technique of preparing hydrocarbons by electrolysis of solutions of salts of fatty acids was Hermann Kolbe. He made significant contributions to the field of organic chemistry, and his work on electrolysis paved the way for the synthesis of organic compounds from inorganic precursors. This process, known as Kolbe electrolysis, demonstrated that organic molecules could be created from inorganic sources, challenging the then-prevailing theory of vitalism in chemistry.
