determining ionic/covalent from elctronegativity

Postby Analiese Machado lec4 » Fri Oct 21, 2016 6:12 pm

If the difference in electronegativity falls between 1.5 and 2, how are we supposed to know whether to draw it as covalent or ionic? I still feel unclear on this.

I think the character of the bond has to be experimentally observed to find a definite answer to whether it's ionic or covalent. Between 1.5 and 2.0 is a gray area, so I doubt we would be expected to know what type of bonds a certain molecule/salt has.
