Alfred Gilmore · Answer 1

The most polar bond has the greatest difference in electronegativity. Thus, we calculate the differences for each bond:

Ca-Cl: 3.16-1=2.16

Fe-O 3.44-1.83=1.61

H-S 2.58-2.2=0.38

F-F=4-4=0

The Ca-Cl bond has the greatest difference in electronegativity and is therefore the most polar.
