Which of the following types of solid is most likely to have a low, but well defined, melting point?

Question

Quizplus · Accepted Answer

Molecular solids have a low, but well-defined melting point because the intermolecular forces between the molecules are relatively weak. These weak intermolecular forces can be overcome with enough thermal energy, leading to a well-defined melting point. In contrast, ionic and network covalent solids typically have high melting points because their crystal structures are held together by strong ionic or covalent bonds. Amorphous solids do not have a defined melting point because they lack a regular, ordered structure.
