Which of these bonds is the most polar?
A.H-F
B.H-Cl
C.H-Br
D.H-I
Explanation
Core Concept
Bond polarity grows with the electronegativity difference between the two atoms. Fluorine heads the Pauling scale at 4.0 while hydrogen sits near 2.2, the widest gap in the list. A bigger difference drags the shared pair harder toward one end, producing the strongest dipole.
Correct Answer
AH-F
