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
