Polar molecules have a dipole moment and they have intermolecular forces that include dipole-dipole interaction. A hydrogen bond is the attraction between a hydrogen bonded to N, O, F atom with N, O, F lone pair. Small molecules that exhibit this effect are HF, H2O and NH3. The example molecules are all polar. The hydrogen bond interaction is stronger than a normal dipole-dipole interaction.
The way I like to look at it is by thinking that in NON polar molecules- atoms share electrons equally, however in polar molecules they do not.
So take a water molecule for an example, which by the way is polar, because it has an unequal distribution of charges. Anyway, back to the water molecule, the reason the water molecule is also polar because the atoms that are bonded together share almost the same amount of electronegativity causing it to have an unequal distribution of charges.
Because there's a lot of difference in electronegativity between H and O, so that molecule will be polar
occurs between nonmetal atoms with n unequal sharing of electrons, electronegativity difference (0.5 to 1.7)
Water is polar because of the difference in electronegativity between oxygen and hydrogen, and the shape of the molecule. Each H-O bond is polar, and, because of the large, electronegative oxygen atom, the molecule is bent so that the partially negative oxygen atom is at one pole of the molecule and the partially positive hydrogen atoms are at the opposite pole of the molecule.
Water (H2O) is a polar a molecule to the electronegativity of oxygen (O) and its dipole moment. Also, the two O atoms are slightly negative as opposed to the hydrogen lending two the molecules bent shape.
Water IS a polar molecule.
Because of its shape, water is a polar molecule.
No, water is not the only molecule that is polar.
Water is polar molecule since oxygen has a higher electronegativity than hydrogen.

Water is more polar because O has an electronegativity value of 3.5 whereas Cl has value of 3.0
naphthalene is only made of two types of atom: carbon and hydrogen. There is little difference in electronegativity between these atoms (how well they can pull on electrons) so there is an equal distribution of electron density across the molecule, thus being NON-POLAR. Water on the other hand is comprised of oxygen and hydrogen atoms, between which there is a large difference in electronegativity. This means that there is an imbalance of charge across the molecule resulting in water being POLAR. a polar molecule is unable to interact with a non-polar molecule as they don't 'have anything in common' in terms of their charge distribution. Naphthalene will dissolve in petrol due to petrol being a non-polar solvent.
The attraction of a particular kind of atom for the electrons of a covalent bond is called its electronegativity. If oxygen and hydrogen had equal electronegativity there wouldn't be any attraction between each molecule of water thus no hydrogen bonds.

A polar molecule
water is a polar, covalent molecule. it doesn't have an unsharing molecule. its also has to do with the 8 properties of water.
