The correct answer is:
high temperature, volcanic storm, reducing atmosphere containing $\mathrm{CH}_4, \mathrm{NH}_2$ etc.
high temperature, volcanic storm, reducing atmosphere containing $\mathrm{CH}_4, \mathrm{NH}_2$ etc.
For the occurrence of chemical evolution by stimulating hypothetical conditions present on early earth. The Miller - Urey experimented.
The primitive earth conditions include high temperature, volcanic storms and reducing environment containing methane $\left(\mathrm{CH}_4\right)$, ammonia $\left(\mathrm{NH}_3\right)$, hydrogen $\left(\mathrm{H}_2\right)$ and water vapour.
They ultimately found that a large number of simple organic compounds including some amino acids such as alanine, glycine and aspartic acid can be synthesised in as during chemical origin of life. In the same experiments formation of sugars, nitrogenous bases, pigments and fats were also observed by others.
