U SURE?

anonymous · Answer

Molecular solid is a solid composed of molecules held together by the van der Waals forces. Because these dipole forces are weaker than covalent or ionic bonds, molecular solids are soft and have relatively low melting temperature.

anonymous · Answer

so...dipole forces are the only forces that hold the molecules together...why not C??

thomaster · Answer

The question is which one is NOT an explanation :D
C is true so it's either A or B and i guess B

anonymous · Answer

oh ya...its NOT the correct ans...right...
