Which of the following may have Frenkel defect? — Solid State Chemistry Question

💡 Solution & Explanation

Frenkel defects are characteristically found in ionic solids where there is a substantial difference in size between the constituent cations and anions, allowing the smaller cation to slip into interstitial sites. Zinc sulphide (ZnS) and silver bromide (AgBr) both frequently exhibit Frenkel defects. Therefore, correct answer is B,C.
