Will you describe polar molecules more briefly.

A polar molecule is a molecule containing polar bonds where the sum of all the bond's dipole moments is not zero. Here the electrons are distributed asymmetrically. For example: Water is a polar molecule because of the way the atoms bind in the molecule such that there are excess electrons on the Oxygen side and a lack or excess of positive charges on the Hydrogen side of the molecule.

Polar covalent bond results with an unequal sharing of electrons. A polar bond is a type of covalent bond between two atoms or more in which electrons are shared unequally. Because of this, one end of the molecule has a slight, relative negative charge and the other a slight, relative positive charge. For example: H₂O; here hydrogen has a slight positive charge and oxygen has a slight negative charge. They are formed when when two elements bond with a moderate difference in electronegativity moderately to greatly, but they do not surpass 1.7 in electronegativity difference.
