What type of intermolecular force holds the molecules together in the crystal?

Quizplus · Accepted Answer

Dry ice is composed of molecules in a crystal lattice, and as such, the intermolecular forces holding the molecules together are London dispersion forces. These forces are a result of temporary dipoles that occur due to the movement of electrons within the molecule, resulting in a weak attraction between adjacent molecules.
