Question

Which of the following is not a characteristic of a crystalline solid?

• A. Definite and characteristic heat of fusion.
• B. Isotropic nature.
• C. A regular periodically repeated pattern of arrangement of constituentparticles in the entire crystal.
• D. A true solid

Answer 1

The correct option is B Isotropic nature.

Crystalline solids are anisotropic in nature, that is, some of their physical properties like electrical resistance or refractive index show different values when measured along different directions in the same crystals.
