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

Options

  1. AAgBr
  2. BCsCl
  3. CKBr
  4. DZnS

Correct answer

A. AgBr

Step-by-step solution

AgBr can exhibit both Schottky and Frenkel defect. Schottky defect in AgBr is exhibited due to the precipitation of both cations and anions. In AgBr , Ag + ion is small in size and when removed from the lattice point, they can occupy the interstitial sites and, hence, shows both Frenkel and Schottky defects.
