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

Single Choice
An example of Frenkel defect is:
A$$NaBr$$
B$$TiBr$$
C$$AgBr$$
Correct Answer
D$$CuBr$$
Solution
Frenkel defect arises due to vacancies at cation site. Actually, the cation moves to another position between two layers (interstitial position) and it is surrounded by a greater number of anions.
In these compounds, the coordination number is low (usually $$4$$ or $$6$$).
Examples : ZnS, AgBr, AgI, AgCl etc.
