Disassociation energy

Postby Jordi M 2I » Wed Nov 18, 2020 12:37 pm

According to the notes I have taken on the lectures so far, Ion-Ion interactions have the largest disassociation energy of -250 kJ/mol. But what about the disassociation for a single covalent bond. I know the strengths can vary depending on atom size, lone pairs, and bond order but In general, are covalent bonds stronger than ionic bonds?

I found a previous chemistry community post that discusses this question! It seems like ionic bonds generally tend to be stronger than covalent bonds (because they give and take electrons rather than share them). However, covalent network solids surpass ionic bonds in strength--examples being diamond etc.

Here is the link to the previous post:

I have already read that ionic bonds are stronger than covalent. I am not sure if their are exceptions.
