The hydrogen bond is an electrostatic attractive force between covalently bonded hydrogen atom of one molecule and an electronegative atom like (F, 0, N) of other molecule. Hydrogen bond is nearly an electrostatic attractive force and not a normal chemical bond. It is very weak (2-10kcal/mol) as compared to a covalent bond (strength 50-100kcal/mol). In intramolecular hydrogen bonding, the two or more than two molecules of the same or different substances are linked to form polymeric aggregate. Intermolecular hydrogen bonding increases the boiling point of the compound and also its solubility in water. Intramolecular hydrogen bonding occurs within two atoms of the same molecule. Intramolecular hydrogen bonding is also called chelation, since it. involves· . ring formation. Intramolecular hydrogen bonding decreases the boiling point of the compound and also its solubility in water. Which of the following compounds is (are) stablised by intramolecular hydrogen bonding?
