Strength of Chemical Bonds
I remember learning in high school that certain types of bonds are stronger than others. What types of bonds are the strongest and what properties contribute to the strength of a bond?
Re: Strength of Chemical Bonds
So, from what I remember. The strongest types of bonds are macromolecular or network covalent bonds, these are compounds such as WiC and SiO2. Following that would be ionic then covalent (Hydrogen bonding > Dipole-Dipole Forces > London Dispersion Forces) and lastly metallic bonds.
Re: Strength of Chemical Bonds
Hello,
The strongest type of bond is an ionic bond. This is because in ionic bonds there is not sharing of electrons, rather the transfer of electrons creates positive and negatively charged particles that have a huge electrostatic charge between them.

Re: Strength of Chemical Bonds
Hi,
Based on what we've learned thus far and my biology class, I think ionic bonds and covalent bonds are pretty similar in strength. Following those would be hydrogen bonds, then van der Waals forces, which are both considered more attractive forces than bonds. In terms of energy, bonds tend to be stronger when they're using less energy, whereas bonds that require more energy will be weaker and more likely to break.

Re: Strength of Chemical Bonds
Hi,
The strongest bonds are covalent bonds and ionic bonds. Therefore, the order from weakest to strongest bonds would be Van Der Waals - Hydrogen Bonds - Ionic Bonds - Covalent Bonds. As the number of electron pairs in the bond increases, the strength of a bond increases. Moreover, as the bond strength increases, the length of the bond decreases due to its strength.

Re: Strength of Chemical Bonds
Are ionic bonds weaker than covalent bonds and what is the reasoning behind that?

Re: Strength of Chemical Bonds
The strength of chemical bonds from weakest to strongest is: Van Der Waals -> Hydrogen Bonds -> Ionic Bonds -> Covalent Bonds

Re: Strength of Chemical Bonds
Hi! For the purposes of this chemistry class ionic bonds are strongest, followed by covalent, then hydrogen, and then van der Waals interactions. Ionic bonds are the strongest due to the attraction between oppositely charged ions. However, in biology courses we're typically dealing with aqueous solutions, so ionic bonds break down and covalent are considered stronger. However, since we're in a chemistry course, it is safe to assume ionic bonds are the strongest. Hope this helps!
