March 22, 2024Question 17318 – NTA UGC NET Dec 2023 Paper-1
Given below are two statements:
Statement (I): Naturally occurring Volatile Organic Compounds (VOCs) generally oxidize to form Carbon Monoxide (CO) and Carbon Dioxide (CO₂)
Statement (II): Anthropogenically emitted VOCs play an important role in the formation of smog
In the light of the above statements, choose the most appropriate answer from the options given below:
Correct Answer: D
Question 28 Explanation:
Statement I is incorrect: While some naturally occurring VOCs can indeed oxidize to form CO and CO2, it’s not their general oxidation product. Many natural VOCs react with other atmospheric compounds in diverse ways, contributing to various processes like ozone formation, cloud formation, and plant defense mechanisms.
Statement II is correct: Anthropogenic VOCs, mainly from human activities like vehicle emissions, industrial processes, and solvent use, play a crucial role in smog formation. These VOCs react with nitrogen oxides (NOx) from similar sources in the presence of sunlight to form ground-level ozone, a key component of smog. This can significantly reduce air quality and cause respiratory problems.
Statement II is correct: Anthropogenic VOCs, mainly from human activities like vehicle emissions, industrial processes, and solvent use, play a crucial role in smog formation. These VOCs react with nitrogen oxides (NOx) from similar sources in the presence of sunlight to form ground-level ozone, a key component of smog. This can significantly reduce air quality and cause respiratory problems.
