Fluorine is more electronegative than oxygen and chlorine. There are many scales used to measure electronegativity. Each is different. Oxygen and chlorine usually have an electronegativity value between 3.2 and 3.5 depending on the scale. Fluorine has an electronegativity of 4, the highest number on the scale. This means that the difference in electronegativity of fluorine and oxygen or chlorine is between 0.5 and 0.8 depending on the scale. This is the amount necessary to form a polar covalent bond.

Flourine
It is polar, albeit only slightly due to oxygen having a larger electronegativity than chlorine.
Polar. Oxygen's electronegativity is 3.44 while Chlorine's is 3.16. Since the valance electrons are not shared equally, we look at electronegativity. It is polar, and oxygen is the atom closer to the negative side.

Fluorine has the highest electronegativity among the three elements. Oxygen is the second most electronegative, while chlorine has a slightly lower electronegativity compared to both fluorine and oxygen.

Fluorine has the highest electronegativity of any element. Its electronegativity is 4. Oxygen has the second highest electronegativity of any element, with an electronegaitivity of 3.5, and chlorine has an electronegativity of 3.16 on the Pauling scale. Note that there is more than one scale for measuring electronegativity. But no matter which scale you use, Fluorine is more electronegative than oxygen, which is more electronegative than chlorine.
Oxygen is more electronegative than chlorine. The electronegativity of oxygen is 3.44 and that of chlorine is 3.16 on the Pauling scale.

FONCl (pronounced fonkle) - the order of electronegativity - F O N Cl - fluorine, oxygen, nitrogen, chlorine
It is polar, albeit only slightly due to oxygen having a larger electronegativity than chlorine.
Polar. Oxygen's electronegativity is 3.44 while Chlorine's is 3.16. Since the valance electrons are not shared equally, we look at electronegativity. It is polar, and oxygen is the atom closer to the negative side.
Fluorine (F): 4.0 Oxygen (O): 3.5 Nitrogen (N) and Chlorine (Cl): 3.0
The element with the highest electronegativity is fluorine (F) at 3.98 in scale. F is followed by oxygen (O) and chlorine (Cl) rated at 3.44 and 3.16 respectively.
The electronegativity of oxygen is 3.44 and for fluorine it is 3.98. The difference in electronegativities is 0.54, so the bond between fluorine and oxygen is polar covalent.
