Strength of bonds

Postby Queena Chu 3E » Sun Oct 25, 2020 11:17 pm

What is the strength of types of bonds from highest to lowest?

Covalent bonds are the strongest bonds, hydrogen bonds are the weakest, and ionic bonds are moderately strong. I hope this helps :)

Ionic bonds are the strongest type of bonds assuming they are not in solution.
Covalent bonds are the second strongest assuming they are not in solution.
Intermolecular forces, weak H bonds with F, O, or N (weak forces of attraction between molecules) that result in things like water cohesion, adhesion, etc, are the least strong.

In biology, covalent bonds are considered to be the strongest however, as many biological chemical systems occur in the presence of water, AKA in solution.
Ionic bonds are "weak" in solution because of a process called disassociation, in which the ions "separate" within a solution they are soluble to.

Hope this helps!

I've learned that covalent bond is the strongest bond when compared to ionic but I also remember that in certain stances, an ionic bond may be very strong as well

I've heard that covalent bonds are the strongest types of bonds!

I am also sure that covalent bonds are the strongest types of bonds

Hi! I just wanted to add that within covalent bonds, single bonds are the weakest bonds and triple bonds are the strongest bonds because they have a stronger hold on the electrons.

Hydrogen bonds are often have the weakest link while covalent bonds have the strongest link with each other. In addition, the bonds with single bonds are ideally weaker than triple bonds.

From highest to lowest I believe the bond strength (in general) is as follows: multiple covalent bonds > single covalent bonds > ionic bonds > hydrogen bonds > van der Waals force.

Covalent bonds are the strongest, then ionic bonds, and hydrogen bonds are the weakest.

Hi! I believe it goes covalent bonds, ionic bonds, hydrogen bonds, and then van der Waals. Covalent bonds are the strongest as they require a high amount of energy to break.

Does it matter if the covalent bond is polar or nonpolar in terms of its strength?

I think that the general order of the strength of bonds is: covalent, ionic, and hydrogen. What I have noticed though is that in some instances people say that ionic bonds are stronger than covalent bonds, but I think this depends on whether the bonds are intramolecular or intermolecular.

I think it depends on whether or not the ionic bonds are in an aqueous environment or not. In the LS7 series we treat ionic bonds as weaker than covalent bonds as all of the chemistry in biology is in an aqueous environment. However, I have also heard that in some cases ionic bonds are stronger than covalent bonds in non-aqueous environments.
