Q.
Which of the following characteristics is/are possessed by non-polar molecular solids?
The Solid State
Solution:
Monoatomic gases such and $He, Ar$ and diatomic molecules like $Cl_2, H_2$, and $I_2$ formed by non-polar covalent bonds are non-polar molecular solids and shows the following characteristics:
(i) Being covalent bonded by weak forces, they have low melting point and are liquid or gases at room temperature and pressure.
(ii) Atoms or molecules are held by weak dispersion force.
(iii) Being non-polar, they are non-conductor.
