Schottky defect appears in — Solid State Chemistry Question

💡 Solution & Explanation

Schottky defects are typically found in highly ionic compounds with high coordination numbers and where cations and anions are of similar sizes, such as NaCl and CsCl. AgBr is unique as it shows both Frenkel and Schottky defects. Thus, all of them exhibit Schottky defects. Therefore, correct answer is D.
