How is water a polar molecule in terms of electronegativity?

Answer 1

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.

Answer 2

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.

Answer 3

Water is a polar molecule because oxygen is more electronegative than hydrogen, resulting in unequal sharing of electrons in the O-H bonds. This causes a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms, creating an overall dipole moment.

Answer 4

Because there's a lot of difference in electronegativity between H and O, so that molecule will be polar

Answer 5

occurs between nonmetal atoms with n unequal sharing of electrons, electronegativity difference (0.5 to 1.7)
