What Makes Water Polar?


Water is polar due to the the higher electronegativity of the oxygen. This causes the shared electrons to be closer to the oxygen, thus creating the polar compound.

The shape of the molecule itself is what makes it polar. The atoms in a water molecule (H2O) are arranged so that the two hydrogen atoms are located to one side of the oxygen atom, instead of in a straight line, or linear pattern. This arrangement causes the electrons in the molecule to orbit around the oxygen atom more often than the hydrogen atoms, thus creating a slight negative charge on the oxygen side, and a slight positive charge on the hydrogen side.
The reason why water is polar, has to do with its asymmetrical shape. C02 is a linear molecule, but H20 is not, as it is bent. Oxygen is being pulled by the hydrogen molecule at an angle.
