Which of the following is not a green house gas?
- A \(\mathrm{CH}_{4}\)
- B \(\mathrm{CO}_{2}\)
- C \(\mathrm{N}_{2}\)
- D \(N_2O\)
Answer & Solution
Correct Answer
(C) \(\mathrm{N}_{2}\)
Step-by-step Solution
Detailed explanation
The correct answer is (3) \(N_2\). \(N_2\) makes up about 78% of the Earth's atmosphere but is not a greenhouse gas. Being a symmetrical diatomic molecule (two identical atoms), it does not absorb infrared radiation radiating from the Earth's surface. In contrast, \(CO_2\),…
