Supramolecular chemistry involves the study of noncovalent interactions within and between molecules. For years chemists have focused on studying molecules and compounds that are held together by covalent bonds and ionic bonds, and how these bonds are formed and broken during chemical reactions. But now researchers in supramolecular chemistry are studying the weaker electrostatic attractions and reversible noncovalent interactions, such as hydrogen bonding.

How are ionic and covalent bonds different from hydrogen bonds?

toga · Answer

Ionic and covalent bonds are different from hydrogen bonds in several ways. Ionic bonds are formed between positively and negatively charged ions, typically between a metal and a nonmetal, and involve the complete transfer of electrons. In contrast, covalent bonds involve the sharing of electrons between atoms.

Hydrogen bonds are a type of noncovalent bond that occurs between a hydrogen atom and an electronegative atom, such as oxygen or nitrogen. Unlike ionic or covalent bonds, hydrogen bonds are much weaker and are formed due to electrostatic attraction between the partially positive hydrogen atom and the partially negative atom it is bonded to.
