ionic vs. covalent bonds

Postby Erica Li 1C » Sun Oct 28, 2018 1:20 pm

In general are ionic bonds much stronger than covalent bonds?

Ionic bonds are generally stronger than covalent bonds in non-aqueous environments because of the big difference in electronegativity between the metal and nonmetal, leading to the transfer of electrons towards the more electronegative atom (e.g. NaCl). Covalent bonds (polar and non polar) have less of that difference than ionics, therefore they are weaker.

Interestingly, covalent bonds can be stronger in the condition that they are held together in complex networks, such as in diamonds.

This depends on the environment because in an aqueous solution covalent bonds would be stronger as ionic bonds would beak and separate due to the polar characteristics of water. However, ionic bonds out of water would be stronger due to the attraction of opposite charges.

In chemistry, ionic bonds are considered to be stronger because of their coulombic attractions between ions. They involve the transfer of electrons, unlike covalent bonds which involve the sharing of electrons. However, as mentioned, in aqueous environments, ionic compounds dissociate into their respective ions, which results in weaker bonds than covalent ones.
