Question

Which of the following compounds is likely to show both Frenkel and Schottky defects in its crystalline form ?

• A. AgBr
• B. CsCl
• C. KBr
• D. ZnS

Answer 1

Answer: (A)

Since $AgBr$ has intermediate radius ratio
$\therefore$ it shows both schottky & Frenkel defects
$\mathrm{ZnS}\to \mathrm{Frenkel}\mathrm{defects}$
$\mathrm{KBr},\mathrm{CsCl}\to \mathrm{Schottky}\mathrm{defects}$
