Lattice energy (∆H∘latt) helps to explain all of the following properties of ionic compounds EXCEPT:
Correct answer: D. Dipole Moment
- A. Structure
- B. Heat of solution
- C. Bonding
- D. Dipole Moment
Explanation
Lattice energy can not explain the dipole moment of ionic compounds. Ionic compounds are held tight in a giant lattice, so the electrostatic forces of attraction are in all directions between all the ions. Thus, ionic lattices are not polar.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
