Frenkel defect is general ly observed in

A
$\mathrm{AgBr}$
B
$\mathrm{AgI}$
C
$\mathrm{ZnS}$
Correct answer
D
All of the above

Solution

When the size of cation is much smaller than the anion then frenkel defect is observed. Hence, $\mathrm{AgBr}, \mathrm{AgI}$ and $\mathrm{ZnS}$ all exhibit Frenkel defect.

Hence, the correct answer is option: 'D'.
