Q86 / 180 · AIIMS 2001 · Chemistry

Crystalline solids have

A
short range order
B
long range order
C
anisotropic distribution
Correct answer
D
All of these.

Solution

Crystalline solids are anisotropic therefore their physical properties e.g. electrical conductivity, thermal conductivity, refractive index are the different in different directions. But amorphous solids, liquids and gases are isotropic (i.e. same physical properties in all directions).

Hence, the correct answer is option: 'D'.
