how do you put the calculation on words?
Water is a polar compound. How do you know? The electronegativity (EN)of O is 3.5. The EN of H is 2.1. So the oxygen pulls the electrons a little closer to itself; therefore, O has a slightly negative charge while H is left with a slightly positive charge (due to the shift in electrons) so the water molecule has a separation of charge and is a dipole. In a non-polar compound the electrons of the bond are shared equally; in a polar compound, they are not shared equally because of the difference in EN.
