Which is the best answer to the question "why do ionic compounds have high melting and boiling points?"

• Ionic compounds have ionic bonds between the ions so

  Breaking these bonds is hard

• Ionic lattices have many strong ionic bonds between the cations and anions

  Breaking these bonds requires lots of energy

• Ionic compounds have a multitude of relatively weak ionic bonds between the alternatively charged ions

• The ionic lattice is strong and breaking the lattice structure is hard to do because it is strong and ionic
