I actually don't think you can say covalent is much much stronger than ionic. Ionic is the interactions between full charges, which I think you're underestimating. Like I said, there's a huge overlap, but I've always been taught that generally ionic > covalent.Strongest to weakest:
covalent >>>>>>> ionic >> ion-dipole = H-bonding > dipole-dipole >>>>> van der waals
Covalent bond is strongest by far since there is a sharing of electrons between two atoms.
Ionic is an electrical attraction between a metal and non-metal... much like the others types of interactions except stronger.
Then explain this:You people talk as if these sort of facts are open to discussion. Please don't confuse a poster by trying to remember an answer that you don't know for sure.
lovefororganic/redchesus are correct.
...which hints at the distinction between covalent and ionic as kinda arbitrary.Right but this isn't theoretical chemistry. And when its a multiple choice test, you can't sit there debating yourself.
A bond is "an electrical force linking atoms ." Ionic bonds form when the electronegativity is great than a difference of 2 on the Pauling Electronegativity chart [sic]. Covalent bonds involve electronegativities lower than a difference of 2.
This is an intermolecular property, not related to intramolecular bond energyConsider the fact that many ionic compounds are solids at room temp (NaCl, KOH, etc.) while the covalent ones are liquids or gases (HCl, CH4, etc.). KCN, for example is a powder, while CH3CN is a liquid. Solubility in water isn't indicative of bond strength btw.
That is not true at all. Not all bonds give off more energy than you supply them to initiate the breaking. If thats the case, you can create a car to run on table salt.Breaking bonds gives off energy.
