What are non-polar molecular solids?
these are those crystalline substances in which the constituent particles are either atoms like those of non polar molecules or of noble gases.atoms or molecules are held togrther by weak dispersion forces.example-solid helium,solid argon.
2)having low melting points
3)generally liquid or gaseous at room temp. and pressure
Such solids have an asymmetrical distribution of electrons and therefore there is no abundance of charge on either side. Opposite charges cancel each other out. Examples are methane, chlorine, hydrogen, oxygen. At room temperature and pressure, they are liquids or gases. The force binding or holding the molecules together in these solids, are Vander Waals forces (weak dispersion or London forces). These forces are weaker than ionic or covalent bonds.
