Question: which among the following will not exhibit frenkel defect?
Answer: Solution : In pure alkali halides, Frenkel defects are not found since the big alkali metal ions cannot get into the interstital sites, Frenkel defects are found in silver halides beacause of the small size of the Ag+ ion. In certain ionic solids such as AgBr both Schottky and Frenkel defeat occur.
