C.) A molecular solid
D.) A network covalent solid

Answer:

C.) A molecular solid

Explanation:

Molecular solids have low melting points, are non-conductive and are insoluble in water. The interactions between the molecules or atoms can be hydrogen bonds, dipole dipole or London dispersion forces.Because they have relatively weak bonds there are easily vaporized and therefore have a low melting point. Although a network covalent solid is non-conductive it has a high melting point due to the strong covalent bonds. The metallic and the ionic solids are both conductive, with the metallic solids having a high melting point.
