Electrical conductivity of graphite is greater in one direction than in another due to
Correct answer: C. Anisotropy
- A. Isomorphism
- B. Cleavage plane
- C. Anisotropy
- D. Symmetry
Explanation
Anisotropy means having a physical property that has a different value when measured in different directions Graphite is a crystalline, anisotropic solid. Graphite can conduct electricity parallel to the planes of a hexagon but its insulator conducts electricity in a direction that is perpendicular to the planes.

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.
