The relatively weak intermolecular forces cause … WebMolecular solids are bad conductors of electricity as there are no free electrons to conduct electricity. Their melting and boiling points are also low, so they vaporize easily. For example, ice, solid CO 2 (dry ice), etc. Molecular solids are again divided into 3 classes as follows. Polar Molecular Solids. These molecular solids have a polar ...
