Students in class argue about whether salt (NaCl) or water (H2O) has stronger intramolecular forces. Which argument is BEST?
Yanka [14]

Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.

Intermolecular forces exists between molecules of the same or different kinds. Water has a dipole moment hence it can interact effectively with the ions in NaCl. This leads to an ion dipole interaction that results in the dissolution of NaCl in H2O.

NaCl is a solid and water is a liquid. Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.

Hence, the best argument that compares the intermolecular interactions in water and NaCl is; salt is a solid and water is a liquid, so water has stronger intramolecular forces.
