Hydrogen Bonding Essay.

HYDROGEN BONDING: Hydrogen bonding is a bonding type consisting of dipole and dispersion forces. A hydrogen bond is the attractive force between a hydrogen atom attached to a molecule and an atom of a different molecule. According to the Pauling scale of electro-negativities of the elements, it can be viewed that the three most electronegative elements in the periodical table are nitrogen, oxygen and fluorine. These are also called heteroatoms. The heteroatoms have a partial …

…This means in other words, that water has an exceptionally high melting point for its molecular mass. In conclusion, hydrogen bonding occurs between a highly delta positive hydrogen atom and a lone pair of electrons on a nitrogen, fluorine or oxygen atom. The hydrogen bonding that occurs is the strongest form of intermolecular, therefore dipole-dipole bonding. Also, due to its geometrical shape and strong bonds, water has a high melting point and also boiling point.
