Which from the following statements is NOT true regarding crystalline solid?

Options

  1. AThere is a regularity and periodicity in arrangement of constituent particles.
  2. BIt is isotropic.
  3. CIt melts at definite temperature.
  4. DIt has different magnitudes for refractive index in every direction.

Correct answer

B. It is isotropic.

Step-by-step solution

All crystalline substances except those having cubic structure are anisotropic, i.e., their properties like refractive index, thermal and electrical conductivity, etc., are different in different directions.
