7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...

Some compounds have interatomic bonds that are partially ionic and partially covalent. Calculate the percentage ionic character of the following compounds: HF, HCl and HBr. Use this information to explain why HF has a higher boiling temperature than HCl (19.4 vs. -85oC), even though HF has a lower molecular weight.
