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).

Detailed explanation-2: -Likewise, a water molecule is ionic in nature, but the bond is called covalent, with two hydrogen atoms both situating themselves with their positive charge on one side of the oxygen atom, which has a negative charge.

Detailed explanation-3: -In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-4: -Water (H2O) is a polar molecule because the electrons of the hydrogen atoms get “pulled” towards the electrons of the oxygen atom. This makes a region of positive charge on the hydrogen atoms and the negative charge on the other end of the molecule, which is the oxygen atom.

Detailed explanation-5: -Polar covalent compound In a polar covalent bond, two atoms share a pair of electrons unequally because of differences in their electro-negativities. The unequal distribution of electrons causes the bonded atoms to acquire fractional positive and negative charges. Examples: Hydrochloride acid and water.
