Answer:
The answer to your question is the first choice (H₂)
Explanation:
Process
Look for the electronegativity of the elements of this exercise
a) H₂ = 2.2 - 2.2 = 0
b) NaF = 3.98 - 0.93 = 3.05
c) HBr = 2.96 - 2.2 = 0.76
d) HS⁻ = 2.58 - 2.2 = 0.38
The molecule that has the smallest difference in electronegativity is H₂
