Best Answer

A molecule is polar is a result of differences in electronegativity; that is, one atom has a stronger pull on electrons than another. Flourine (F) is more electronegative than chlorine (Cl), and so tends to pull electrons to its side of the molecule. This makes FCl polar.

F2 consists of two atoms of fluorine, which are identical and thus have the same electronegativity. Therefore, the molecule is nonpolar.
