2.14A ION-ION FORCES
- The strong electrostatic lattice forces in ionic compounds give them high melting
points. - The boiling points of ionic compounds are higher still, so high that most ionic
organic compounds decompose before they boil.

2.14B DIPOLE-DIPOLE FORCES
- Dipole-dipole attractions between the molecules of a polar compound:
Figure 2.7 Electrostatic potential models for acetone molecules that show how
acetone molecules might align according to attractions of their partially
positive regions and partially negative regions (dipole-dipole
interactions).
