The correct statement(s) regarding defects in solid is (are) — Solid State Chemistry Question

💡 Solution & Explanation

Frenkel defect is favoured by a large difference in ion sizes, making A false. It is often referred to as a dislocation defect as an ion physically dislocates from a normal lattice site to an interstitial void. An F-centre forms exactly when an electron gets trapped in an anionic vacancy. Schottky defects demonstrably lower crystal density, modifying physical properties. Therefore, correct answer is B,C.
