In anisotropic crystals, which property does not change with the change in direction of crystalline structure?

Correct answer: C. Molar mass

  • A. Electrical conductance
  • B. Thermal conductance
  • C. Molar mass
  • D. Refractive index

Explanation

The property that does not change with the change in the direction of crystalline structure in anisotropic crystals is C, molar mass. Molar mass is an intrinsic property of a substance and remains constant for that substance, regardless of its crystalline orientation.

About Crystalline Solids

Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
