Question

In a solid lattice, the cation has left a lattice site and is located at an interstitial position. Such a lattice defect is called:

• A. intrinsic defect
• B. vacancy defect
• C. frenkel defect
• D. schottky defect

Answer 1

The correct option is C frenkel defect

Frenkel defect arises due to a vacancy at a cation site. Actually, the cation moves to another position between two layers (interstitial position) and it is surrounded by a greater number of anions.
