What type of intermolecular force in NaCl?

Answer 1

Dipole-dipole forces, as Na is positive, however Cl is negative. They cross each other out, but when coming into contact with other molecules, Na, the positive, attracts the Cl of the other molecule, which is the negative part, and so on.

Answer 2

Solid sodium chloride consists of a lattice of sodium and chloride ions. There are no sodium molecules in the solid, and therefore no intermolecular forces.

In solution sodium chloride is 100% dissociated and there are no molecules.

Vapour phase sodium chloride is iapparently a complex mixture of monomeric NaCl dimeric NaCl and linear polymers. Theoretically the monomer should be highly polar and more like an ion pair than a covalent molecule, nad we would expect a high dipole moment.

Answer 3

Sodium chloride has an ionic bond.
