What is H-Bonding?
Hydrogen, which is bonded covalently with strongly electronegative element, can again form an extra weak physical bond with electronegative element; such weak bond is known as hydrogen bond, i.e. The electrostatic force that binds H-atoms of one molecule with electronegative atom of the other molecule of the same substance or of the different compound or within the same molecule is known as H-bonding.
Example:
+δ- δ +δ- δ +δ- δ
……….H-F…………..….H-F………………..H-F………
Hence, Hydrogen –bond is electrostatic in origin. It – is represented by (…………) dotted line.
It is of Two Types:
……….H-F…………..….H-F………………..H-F………
Hence, Hydrogen –bond is electrostatic in origin. It – is represented by (…………) dotted line.
It is of Two Types:
- Inter-Molecular H-Bonding [Association]
- Intra-Molecular H-Bonding [Chelation]
