Detailed explanation-1: -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). We say that the water molecule is electrically polar.
Detailed explanation-2: -When a positive charge brings closer to the polar molecules, due to the electric field of the positive charger, the oxygen atom (it has a negative charge) in polar molecules experiences an attractive force, while the hydrogen atom (it has a positive charge) gets repelled.
Detailed explanation-3: -As a result, the water molecule is “polar”, meaning the molecule has an unequal distribution of charge. The oxygen atom pulls the electrons away from the hydrogen atoms resulting in the oxygen atom having a partial negative charge (-
