Who produced methane in 1856 by bringing carbon disulphide vapour in contact with red-hot copper and hydrogen sulphide?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Marcelin Berthelot.
In 1856, French chemist Marcelin Berthelot successfully produced methane (CH₄) by passing carbon disulphide vapour over red-hot copper in the presence of hydrogen sulphide. This experiment demonstrated the synthetic formation of organic compounds from inorganic materials, a major milestone in organic chemistry.
Other options:
-
Antoine Lavoisier is known as the father of modern chemistry for naming oxygen and hydrogen.
-
John Dalton proposed the atomic theory.
-
Hennig Brand discovered phosphorus in the 17th century.
