H2O is a polar molecule because it is not a symmetrical molecule.It is a V shaped/bent molecule. It has 2 lone pairs in the top of oxygen molecule and 2 H atoms in the bottom of the molecule. In the moalecule OF2, Flourine is more electronegatice than O. But in H2O, O was more electronegative, this is why in OF2 the dipole direction is opposite for lone pair and OF bond. But in H2O, the direction of lone paid dipole monent and bond dipole moment is in the same direction. Hence H2O has more dipole moment than OF2.
