WebNov 2, 2024 · Generally speaking, ionic bonds are stronger than covalent bonds. I also agree that ionic bonds are stronger than covalent bonds. Ionic bond is generally stronger because the ion-ion force that exists in ionic bonding is the strongest. In covalent bonds, electrons are shared, which doesn't generate a force as strong as that in ionic bonding. WebAug 10, 2015 · Not all ionic reactions are not faster, i.e. have a larger rate constant than those between neutral species, however, at similar activation energies there are effects that only ionic reactions suffer. There are two considerations, the dielectric constant of the solvent used, water, hexane, ethanol, acetone etc., and the relative charges on the ions, …

WebCompounds can be classified as ionic or covalent. Molecules are the simplest unit of a covalent compound, and molecules can be represented in many different ways. Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens ...
