Match List - I (Defects) with List - II (shown by). Choose the correct answer.
Column I
- A. Frenkel defect
- B. Schottky defect
- C. Vacancy defect
- D. Interstitial defect
Column II
- I. non-ionic solids and density of the solid decreases
- II. non-ionic solids and density of the solid increases
- III. ionic solids and density of the solid decreases
- IV. ionic solids and density of the solid remains constant
Correct answer: A → IV, B → III, C → I, D → II
Detailed Solution
Frenkel and Schottky defects are shown by ionic solids; density remains constant in Frenkel and decreases in Schottky. Vacancy and interstitial defects are shown by non-ionic solids; density decreases in vacancy defect and increases in interstitial defect.
