In a solid lattice, the cation has left a lattice site and is located at an interstitial position, the lattice defect is:
Correct answer: C. Frenkel defect
- A. Interstitial defect
- B. Vacancy defect
- C. Frenkel defect
- D. Schottky defect
Explanation
In a solid lattice, the cation has left a lattice site and is located at interstitial position, the lattice defect is Frenkel defect. This defect is observed in compounds having low coordination number and low radius ratio. It is also found in compounds having highly polarizing cation and an easily polarisable anion.

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.
