Question

The ratio of $C{H}_4,N{H}_3$ and $H_2$ used by Miller in his spark discharge apparatus was

• A. 2 : 1 : 2
• B. 1 : 1 : 2
• C. 1 : 2 : 2
• D. 2 : 1 : 1

A- The Miller-Urey experiment or Miller experiment was an experiment that instigated the condition which were thought to be present in early earth or primitive earth. Hecreated electric discharge in a closed flask containing a mixture of ammonia(NH3), methane(CH4), hydrogen(H2) and water vapour(H2O) at 800 degree celcius and observed formation of amino acids The ratio of CH4,NH3 and H2 was 2:1:2.
