Solid State Question 268
Question: Which of the following statements are correct in context of point defects in a crystal-
Options:
A) AgCl has anion Frenkel defect and $ CaF_2 $ has Schottky defects
B) AgCl has cation Frenkel defects and $ CaF_2 $ has anion Frenkel defects
C) AgCl and $ CaF_2 $ have anion Frenkel defects
D) AgCl and $ CaF_2 $ have Schottky defects
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Since $ A{{g}^{+}} $ (cation) is smaller than $ C{{l}^{-}} $ (anion) and hence cation is present in voids. In $ CaF_2,C{{a}^{2+}} $ is smaller.
