A few examples of compounds which exhibit hydrogen bonding are discussed belo..

Hydrogen bond is much weaker than a covalent bond. The strength of hydrogen bond ranges from 10-40 kJ mol - 1 while that of a normal covalent bond is 400 kJ mol - 1 . Thus, a hydrogen bond is about one-tenth of the ..

This occurs when the hydrogen bonding is between H-atom of one molecule and an atom of the electronegative element of another molecule. For example (i) hydrogen bond between the molecules of hydrogen fluoride. (ii) hydrogen ..

This bond is formed between the hydrogen atom and an atom of the electronegative element (F,O,N) , of the same molecule . Intramolecular hydrogen bond results in the cyclization of the molecules and prevents their association. Consequently, the effect of thi..

Conditions for Hydrogen Bonding - Since hydrogen bond comes into existence as a result of dipole-dipole interactions between the molecules, therefore, following conditions are required for effective hydrogen bonding. (i) Hydrogen..

Since hydrogen bond comes into existence as a result of dipole-dipole interactions between the molecules, therefore, following conditions are required for effective hydrogen bonding. (i) Hydrogen atom should be bonded to a highly electrone..

Association The weak electrostatic interactions of intermolecular hydrogen bonding, causes two or more molecules of a compound to exist as aggregates or associated molecules. This is seen in water molecules, which undergo molecular association. Alcohols and carboxyl..

Hydrogen bond is an intermolecular force of attraction that exists in the molecules that have hydrogen atom bonded to nitrogen, oxygen, or fluorine. Hydrogen bond is a strong dipole-dipole attractio..
