Question

Which one of the following pairs of gases does not represent the greenhouse gases?

• A. \(CH_4, N_2O\)
• B. \(CFCs, O_3\)
• C. \(O_3, CO_2\)
• D. \(N_2, CO\)

Hint:

When considering greenhouse gases, focus on their ability to absorb and emit infrared radiation, which is not significant in the case of \(N_2\) and \(CO\).

Answer 1

The Correct Option is D

Analysis of Gases:
Methane (\(CH_4\)) and Nitrous Oxide (\(N_2O\)) are well-known greenhouse gases. CFCs and Ozone (\(O_3\)), although problematic for the ozone layer, also have greenhouse effects. \(CO_2\) is a primary greenhouse gas. 
Identifying Non-Greenhouse Gases:
Nitrogen (\(N_2\)) and Carbon Monoxide (\(CO\)) are not typically classified as greenhouse gases. \(N_2\) is inert and does not absorb infrared radiation significantly, while \(CO\)'s contribution to the greenhouse effect is minimal compared to \(CO_2\).
