A solid substance has a very low melting point, is soft, and does not conduct heat or electricity. This substance is probably a(n)________ solid.

Question

Quizplus · Accepted Answer

This substance is likely a nonpolar molecular solid because it has a low melting point (indicating weak intermolecular bonds) and does not conduct heat or electricity (indicating a lack of mobile charged particles). The fact that it is soft also suggests weak intermolecular forces. Metallic, ionic, and network solids typically have high melting points and conduct heat and electricity. Polar molecular solids may have higher melting points and may be able to conduct electricity if they have mobile charged particles, but they would not be expected to be soft.
