Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
The presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.
The atmosphere has been divided into five layers based on the availability and the composition of different elements.
<h3>Troposphere</h3>
The troposphere has been the lowest layer of the atmosphere. It has been closed to the earth surface and provides with clouds and maintain weather.
The gases on the troposphere are used by the organisms for living purpose. The ozone has been a harmful gas for living organisms.
Thus, the presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.
