What is stronger ionic or covalent?

[virtualmaster999]

Hi everyone!

Kinda confused on this. I've heard people say both ways, that sometimes it depends, etc

What should I go by for the DAT?

Thanks!

Ionic.


Unless you are talking about network covalent, then I don't really know.

As a general rule ionic compounds are stronger. This is reflected in physical properties such as melting and boiling points. The melting point of LiF is 845 celsius glucose is 146 celsius.

Hope this helps

what about network covalent vs ionic? Depends on molecule?

This is not so clear cut because some network covalent compounds are stronger than ionic and some are weaker. Both are very strong and can not be easily compared. For example, diamond is a network solid and so is graphite but have very different melting points.

Hope this helps.
