Verified Answer
Primitive atmosphere was made up of themixture of :[CPMT 81]a)Oxygen, ...
The primitive atmosphere of earth was reducing atmosphere with little or no oxygen but was rich in water vapour, carbon monoxide, carbon dioxide, nitrogen and hydrogen. Thus, oxygen was not present in primitive atmosphere. The high temperature, UV light and lightening provided energy for chemical reactions between hydrogen and free oxygen, nitrogen and carbon to form, ammonia, methane and cyanides. Owing to the high temperature of earth, water was present in form of superheated steam and ammonia, methane and cyanides were present in gaseous form.
Therefore, the correct answer is option C.

Primitive atmosphere was made up of themixture of :[CPMT 81]a)Oxygen, ...
The correct answer is option 'c': Hydrogen, steam, methane, ammonia.
Explanation:
The primitive atmosphere of the Earth is believed to have formed around 4.6 billion years ago, shortly after the planet's formation. This early atmosphere was primarily composed of gases released from volcanic activity and the outgassing of the Earth's interior.
1. Hydrogen:
Hydrogen gas (H2) was abundant in the primitive atmosphere. It was released from volcanic eruptions and was a major component of the early atmosphere.
2. Steam:
Water vapor (H2O) in the form of steam was also present in the primitive atmosphere. The high temperatures from volcanic activity caused water on the Earth's surface to evaporate and enter the atmosphere.
3. Methane:
Methane (CH4) is a greenhouse gas that was present in the primitive atmosphere. It was released by volcanic activity and the activity of early microorganisms called methanogens.
4. Ammonia:
Ammonia (NH3) was also present in the primitive atmosphere. It was released by volcanic activity and the decomposition of organic matter.
These gases, when combined, formed a primitive atmosphere that was different from the current composition of the Earth's atmosphere. This early atmosphere lacked significant amounts of oxygen, which is abundant in the present-day atmosphere.
It is important to note that the composition of the primitive atmosphere is still a topic of scientific research and debate. Different theories propose different compositions, and the exact proportions of these gases are not known with certainty. However, the most widely accepted theory suggests that hydrogen, steam, methane, and ammonia were major components of the primitive atmosphere.
The primitive atmosphere played a crucial role in the early Earth's climate and the development of life. Over time, various processes such as volcanic activity, the emergence of photosynthetic organisms, and the formation of oceans led to changes in the composition of the atmosphere, eventually leading to the oxygen-rich atmosphere we have today.
