Do ionic compounds have intermolecular forces?

Click For Summary
SUMMARY

Ionic compounds such as NaCl and K2O do not possess intermolecular forces due to their structure as ionic lattices, which are held together by strong electrostatic forces between charged ions. The basic unit of ionic compounds is the formula unit, not a molecule, which further confirms the absence of intermolecular forces. Additionally, while all atoms and molecules exhibit dispersion forces, metallic atoms primarily experience these forces in specific contexts, as noted in Tro's textbook.

PREREQUISITES
  • Understanding of ionic bonding and electrostatic forces
  • Familiarity with the concept of formula units versus molecular compounds
  • Knowledge of dispersion forces and their applicability to different types of atoms
  • Basic chemistry principles regarding atomic structure and interactions
NEXT STEPS
  • Research the properties of ionic compounds and their lattice structures
  • Explore the differences between ionic and molecular compounds in detail
  • Study the role of dispersion forces in various types of bonding
  • Examine the conditions under which ionic compounds may exhibit molecular behavior
USEFUL FOR

Chemistry students, educators, and anyone seeking to deepen their understanding of ionic compounds and their properties.

Homework Statement


Do ionic compounds such as NaCl and K2O have intermolecular forces?

2. The attempt at a solution
I got stuck conceptually. NaCl and K2O are ionic compounds. Their basic unit is formula units. They are not molecular compounds. Ionic compounds are held together by electrostatic forces. So they don't have intermolecular forces?

Technically there is no such thing as a molecule of an ionic compound (unless we are talking about some exotic conditions, where they can be gaseous).

They don't have intermolecular forces. One more question: do metallic atoms have dispersion forces? In the textbook by Tro, "Since all atoms and molecules have electrons, they all have dispersion forces."
