1.	Which of the following is true based on the strength of the bond?(a) Ionic > Covalent > Vanderwaal> Hydrogen(b) Covalent > Ionic > Vanderwaal > Hydrogen(c) Covalent > Ionic > Hydrogen > Vanderwaal(d) Covalent > Ionic > Hydrogen = VanderwaalThis question was addressed to me by my college professor while I was bunking the class.The origin of the question is Biological Molecules Structures and Functions topic in division Structures and Functions of Biological Molecules of Cell Biology
Answer» Right choice is (b) Covalent > Ionic > Vanderwaal > HYDROGEN The explanation: Intramolecular bonds are called covalent bonds and are far stronger that intermolecular forces (or bonds). The latter are usually ranked as follows: ionic > Vanderwaal > hydrogen. Hydrogen bonding includes inter MOLECULAR interactions with permanent dipoles (and partial charges) between hydrogen atoms and a few other elements. Vander WAALS interactions are based on random and instantaneous dipoles which last for fractions of a SECOND in long, polarizable bonds.
