Myschool Review this, the answer should be NEON

A. Copper: Copper is a metallic element. Metallic bonding, which involves the delocalization of electrons, is the primary type of bonding in metals. Van der Waals' forces are generally negligible in metals due to the nature of metallic bonding.

B. Graphite: Graphite is composed of layers of carbon atoms arranged in a hexagonal lattice. It exhibits van der Waals' forces between the layers, known as London dispersion forces.

C. Neon: Neon is a noble gas composed of individual atoms. Noble gases are typically monatomic and do not form molecules, so there are no van der Waals' forces between them.

D. Iodine crystals: Iodine molecules in solid iodine crystals are held together by weak van der Waals' forces (specifically, London dispersion forces).

So, the substance that does not have van der Waals' forces is:

C. Neon
