Which German chemist used the technique of preparing hydrocarbons by electrolysis of solutions of salts of fatty acids?

Correct option is D

The correct answer is (D) Hermann Kolbe

Explanation:
• The method of preparing hydrocarbons by electrolysis is called Kolbe’s electrolysis.
• It involves electrolysis of aqueous solutions of salts of fatty acids.
• The reaction results in formation of alkanes with even number of carbon atoms.
• This technique was developed by a German chemist.
• Hence, the chemist was Hermann Kolbe.

Information Booster:
• Kolbe’s electrolysis is an important topic in organic chemistry.
• It is used to prepare symmetrical alkanes.
• Example: Sodium acetate gives ethane on electrolysis.

Additional Knowledge (Incorrect Options):

(A) Cecilia Payne
• An astronomer known for work on stellar composition.
• Not related to organic chemistry reactions.

(B) Marcellin Berthelot
• A French chemist known for thermochemistry.
• Did not develop electrolysis of fatty acid salts.

(C) Giulio Natta
• Known for polymer chemistry and stereoregular polymers.
• Not associated with Kolbe’s electrolysis.
