Question:
Which of the following is not a green-house effect gas?
Which of the following is not a green-house effect gas?
Show Hint
The main air components ($N_{2}$ and $O_{2}$) are NOT greenhouse gases. Only more complex molecules like $CO_{2}$ and $CH_{4}$ trap heat.

- $N_{2}O$
- $CH_{4}$
- $CO_{2}$
- $N_{2}$
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Greenhouse gases are those that trap heat in the atmosphere by absorbing infrared radiation.
Step 2: Meaning
Common greenhouse gases include Carbon dioxide, Methane, Nitrous oxide, and water vapor.
Step 3: Analysis
$CO_{2}, CH_{4},$ and $N_{2}O$ are well-known greenhouse gases. Nitrogen ($N_{2}$) makes up 78% of the atmosphere but does not absorb infrared radiation and thus does not contribute to the greenhouse effect.
Step 4: Conclusion
Nitrogen ($N_{2}$) is not a greenhouse gas. Final Answer: (D)
