(d) Molecular solids are the solids in which atoms or molecules are held together by London dispersion forces, dipole-dipole interactions.or hydrogen bonds. They have low melting points and flexibility and are poor conductors. HCl has dipole-dipole forces. H2O has hydrogen bonding. CCl4 has London dispersion forces. Thus, these are molecular solids. SiO2 is a covalent or network solid.
