Statement I: Frenkel defect involving the migration of ions to interstitial sites is more likely for covalent compounds and for large (and highly polarisable) anions.
Statement II: Large polarisable anions make it easier to accommodate the displaced cations and minimise repulsive effect.
Statement II: Large polarisable anions make it easier to accommodate the displaced cations and minimise repulsive effect.
View answer and explanation
Correct option: A
Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I
Option A is correct because Frenkel defects are more likely in covalent compounds with large, polarizable anions, as these conditions facilitate cation displacement and minimize repulsion.
