Question

Quizplus · Accepted Answer

Osmium tetroxide is a molecular crystal because it consists of discrete molecules held together by weak Van der Waals or London dispersion forces. This is evident from its softness and low melting point, as well as the fact that it does not conduct electricity in the liquid state.
