Electronegativities
F = 4.0
Cl = 3.0
I = 2.5

4.0 - 3.0 = 1.0

3.0 - 2.5 = 0.5

The bond between Cl and F is more polar

Look up the electronegativities of F, Cl and I.
Calculate the differences between F and Cl, and Cl and I.
The one with the bigger difference is the more polar.

Cl-F

F is the most electronegative element in the entire periodic table
