What is special about hydrogen bonds?
Hydrogen bonding is a very special intermolecular force that occurs in polar molecules when a hydrogen atom is bonded to a highly electronegative atom. The only possible atoms with a high enough electronegativity are N, O, and F. They are so strong that they seem like weak covalent bonds. Thus, the name hydrogen bond.Click to…
Hydrogen bonding is a very special intermolecular force that occurs in polar molecules when a hydrogen atom is bonded to a highly electronegative atom.

Likewise, people ask, why hydrogen bonding is the strongest?Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength. The hydrogen bond is one of the strongest intermolecular attractions, but weaker than a covalent or an ionic bond. Hydrogen bonds are responsible for holding together DNA, proteins, and other macromolecules.Also, what can hydrogen bond? A hydrogen bond is the attractive force between the hydrogen attached to an electronegative atom of one molecule and an electronegative atom of a different molecule. Usually the electronegative atom is oxygen, nitrogen, or fluorine, which has a partial negative charge. Similarly, you may ask, why are hydrogen bonds important? Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water’s unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.Why is hydrogen bonding stronger than other dipole dipole attractions? Re: H Bonds stronger than dipole-dipole However, a hydrogen bond is specifically between a partially positive hydrogen atom and a partially negative atom (N, O, or F). Since N, O, and F, are much more electronegative than hydrogen, the dipole is stronger, therefore the polarity is stronger.
