A Levels Chemistry

The ability of an atom in a covalent bond to attract electrons to itself is called its electronegativity.
The greater the difference between the electronegativities of the two atoms in the bond, the more
polar is the bond.
Which pair will form the most polar covalent bond between the atoms?
A chlorine and bromine
B chlorine and iodine
C fluorine and chlorine
D fluorine and iodine
