Question

Frenkel defect generally appears in:

• A. $AgBr$
• B. $ZnS$
• C. $AgI$
• D. All of the above

Answer 1

The correct option is D All of the above

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.

Frenkel defect is shown by ionic substance in which there is a large difference in the size of ions.

Frenkel defect generally appears in $ZnS,AgBr,AgI,AgCl$ etc.
