what is different between polar and non-polar molecule?

Question

anonymous · Answer

Polar Molecule There is a Charge Seperation Eg: HCl    H+     cl^-...this arises Due to Electro negativity of Atoms Present

anonymous · Answer

Polar Molecules are Soluable in Water....and Non Polar Molecule Do not have Charge Seperation....)...For More Details Google it..:)......Hope this helps

but i don't understand  well 
i know  water  is polar  but  why?????????

Water (H2O) is a polar because of the difference in electronegativity between hydrogen and oxygen. The highly electronegative oxygen atom attracts electrons or negative charge to it, making the region around the oxygen more negative than the areas around the two hydrogen atoms.Each water molecule is bent so that the positive portions of the molecule (the hydrogen atoms) are flexed away from the two filled orbitals of the oxygen.
