Physico-Chemical Structure or Bonding

Hydrogen bond is one of the most essential concepts in supramolecular chemistry or molecular sociology . It has significant ramifications on molecular biology and materials science . The term and concept `hydrogen bond ' has only emerged after 1930 however the general notion of weak but specific interaction that involves hydrides is much older (Webmaster 2005

Hydrogen bond refers to the attractive force between the hydrogen that has to an electronegative atom of a molecule and an electronegative atom of an unlike molecule . It is a special case of

dipole forces wherein the electronegative atom is usually an oxygen nitrogen or fluorine - elements that have a partial negative charge except for hydrogen which possesses a partial positive side (Ophardt c 2003

Hydrogen bonding happens when two electronegative atoms , for instance nitrogen and oxygen , interact with the same hydrogen . Normally , the hydrogen is covalently to an atom which is referred as the donor . But it interacts electrostatically with the other , known as acceptor . The interaction is primarily because of the dipole amid the electronegative atoms and proton (Day 1996 . It is the strongest molecular force and passes on some strange properties to a myriad of substances namely water , proteins and nucleotides (Structure and Bonding : The Hydrogen Bond n .d

Hydrogen bond is one of the most important components of biological life . If there is no hydrogen bond , there will be no life because it holds the double helix of deoxyribonucleic acid (DNA ) together (Emsley 2000
