Web9 feb. 2012 · The maturity of a science can be measured in terms of successively improved operational definitions of its terms of reference. From this perspective, the science of hydrogen bonding remains in a somewhat immature and unsettled state, reflecting current uncertainties in empirical diagnosis, theoretical origin, and formal definition of this … WebSubstances with covalent bonds often form molecules with low melting and boiling points, such as hydrogen and water. These substances have strong covalent bonds within the molecules (between...
WebHydrogen bonds are not really bonds but intermolecular forces - weak forces which arise between molecules. Hydrogen bonds are the strongest kind of intermolecular force, but are still much weaker than the covalent bonds that hold the atoms together inside a molecule - remember the intermolecular forces operate from one molecule to another. WebIt mainly occurs between an electronegative atom and a hydrogen atom. Unlike the covalent bond, whose strength varies within the factor of ∼4 (30–120 kcal mol−1), the hydrogen bond is less constrained in its physical and geometrical properties. Hydrogen bonds vary in strength by 20-fold (2–40 kcal mol−1).
