Hydrogen Bond: Formation, Structure and Properties of Hydrogen Bonds in Water

The life was originated and started its evolution in water. Without water, life could not have existed on this planet. The properties of water, both physical and chemical, enabled water as the ‘solvent of life’. The water possesses some unusual physical and chemical properties. These ‘unusual properties’ of water makes water as the solvent of life. The unusual properties of water are due to presence of Hydrogen Bonds in them. The present post describes the method of formation of hydrogen bonds in water its properties.

How Hydrogen Bond is formed in Water?

Ø  Water is a polar solvent.

Ø  The polarity of a molecule due to uneven of distribution charges in them.

Ø  Uneven charge distribution causes a dipole formation.

Ø  One part (pole) of water molecule is slightly positive.

Ø  The other part (pole) of water molecule is slightly negative.

Ø  This type of difference in the distribution of positive and negative charges in a molecule is due to the huge difference in the electronegativity of the atoms in them.

Ø  Electronegativity is the ability of an atom to attract bonded pair of electrons towards its nucleus.
