WebDry ice, or solid carbon dioxide, is a perfect example of a molecular solid. The van der Waals forces holding the CO 2 molecules together are weak enough that dry ice sublimes it passes directly from the solid to the gas phase at -78 o C. Covalent solids, such as diamond, form crystals that can be viewed as a single giant molecule made up of an ...

WebClassify C 60, BaBr 2, GaAs, and AgZn as ionic, covalent, molecular, or metallic solids and then arrange them in order of increasing melting points. Answer: C 60 (molecular) < AgZn (metallic) ~ BaBr 2 (ionic) < GaAs (covalent). The actual melting points are C 60, about 300°C; AgZn, about 700°C; BaBr 2, 856°C; and GaAs, 1238°C.

Summary WebMar 31, 2024 · So, the correct answer is Option A. Note: It is quite confusing between choosing graphite as a molecular solid or covalent solid. But, the type of solid is determined by the type of bonds that help the molecules to maintain the solid structure of a solid. Thus, graphite is a molecular solid.
