Question

Who produced methane in 1856 by bringing carbon disulphide vapour in contact with red hot copper and hydrogen sulphide?

• A. Antoine Lavoisier
• B. Marcelin Berthelot
• C. Hennig Brand
• D. John Dalton

Answer 1

Answer:

B. Marcelin Berthelot

• Marcelin Berthelot (1827–1907) was a prominent French chemist and politician. He is renowned for his extensive work in thermochemistry, organic chemistry, and the synthesis of organic compounds. • His experimental work in 1856, involving the reaction of carbon disulfide (CS2) vapour with red-hot copper and hydrogen sulfide (H2S), led to the production of methane (CH4). This was a significant achievement in understanding the synthesis of hydrocarbons.
