Bond strengths

Postby sarahwu3a » Wed Nov 06, 2019 2:04 pm

Is it possible to have a bond that is both longer and stronger in comparison to another bond? Or should we assume that if a bond is longer, it is weaker than the bond in comparison?

No, assumed that if the bond is longer, then it is also weaker.

Hope this helps!

Bond length and bond strength have an inverse relationship. A longer bond such as a single bond is weaker, while a shorter bond such as a triple bond will be stronger.

I would say that in general, say that if a bond is shorter, it is stronger. I am not sure if there are any exceptions to this rule.

Usually when a bond is shorter it is stronger, because there are more electrons that are shared between ions which result in a stronger pull between the electrons and the atoms' nuclei. The same goes for why a longer bond is weaker.

I think that for intramolecular bonds, the shorter it is the stronger it is. This might not be the case for IMF's between molecules though.

A longer bond means a weaker bond as the interaction between the atoms is weaker. Shorter bonds mean a strong pull between the nuclei of the two atoms and thus it requires more energy to break which means it is stronger.

when the bonds get shorter they get increasingly stronger. ex: single bonds being longest and weakest, triple bonds being shortest and strongest.

Usually if a bond is shorter, it's because there are more electrons involved and the pull is greater, therefore decreasing the length of the bond. This makes the shorter bonds stronger.

If a bond is longer, it is weaker than a bond that is shorter. This is why triple bonds are stronger than double bonds that are stronger than single bonds. Triple bonds have the shortest bond length and single bonds have the longest.
