Strength of ionic v covalent bonds

Postby Jessica Yang 1J » Thu Dec 07, 2017 9:32 am

Do ionic bonds (with larger electronegativity difference) tend to have a lower or higher disassociation energy compared to covalent bonds?

Ionic bonds have higher dissociation energy that covalent bond because the polarity of ionic compounds makes it easier for them to break apart in solution. For example, NaCl is highly dissociative in water because of its polarity.

I believe the electromagnetically difference is referring to whether a compound is ionic or covalent bond. If the electronegativity difference between two atoms is greater than 2 then the compound is ionic. If the electronegativity difference between two atoms is less than 1.5 then it's a covalent bond.

Bonds that have a shorter bond length (i.e a triple bond) have a higher dissociation energy and those that have longer bonds have a lower dissociation energy (i.e. single bonds).
