5.7 - Polarity of Molecules
Polarity of H2O
It is a well-known scientific fact that:
|
Water, H2O,
is bent-shaped with a bond angle of 104.5o. Water is a polar
molecule.
|
Oxygen is more electronegative than hydrogen. So, each hydrogen-oxygen double (H-O) is polar covalent with a partial negative charge on the oxygen atom.
Water has two polar covalent bonds and it is a polar molecule. |
Let's add up all the bond dipole moments (Vector 1 and Vector 2) in the water molecule.
There is a net dipole moment. H2O is a polar molecule.
