Which of the following statement(s) is/are incorrect regarding the defects in solids? — Solid State Chemistry Question

💡 Solution & Explanation

Doping introduces localized electronic point defects (impurity defects), not extended line or dislocation defects. Metal deficient defects via extra anions in interstitial sites do not practically occur because bulky anions cannot easily fit into the smaller interstitial voids. Thus, statements C and D are incorrect. Therefore, correct answer is C,D.
