Detailed explanation-1: -Polar end of molecule attracts opposite charges on another water molecule (acts like magnet).
Detailed explanation-2: -When an oxygen atom joins with two hydrogen atoms to make a water molecule, it shares an electron with each. But it also has electrons it doesn’t share. As a result, the water molecule has + and – poles, like a magnet. These poles attract each other, forming weak links called hydrogen bonds.
Detailed explanation-3: -Water is a Polar Covalent Molecule The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Detailed explanation-4: -A peculiar thing about water molecules is their polar nature. Polar molecules have electric poles. A water molecule has a positive and a negative pole, just like a magnet except that a magnet has magnetic poles, not electric ones.
Detailed explanation-5: -Because the hydrogen ions carry a positive charge and the oxygen ion a negative one, this arrangement gives the molecule a net polarity, much like a magnet.
