Question:
Which of the following exhibits Frenkel defects?
Which of the following exhibits Frenkel defects?
Show Hint
Frenkel defects occur when a cation leaves its lattice site and moves to an interstitial site, commonly found in silver halides.
Updated On: Feb 7, 2025
- Sodium chloride
- Silver bromide
- Graphite
- Diamond

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Frenkel defects.
- Frenkel defects occur when a smaller ion (usually a cation) moves to an interstitial site, creating a vacancy.
Step 2: Identifying the correct answer.
- \( {NaCl} \) and diamond do not show Frenkel defects.
- Graphite does not show this defect as it has a layered structure.
- \( {AgBr} \) exhibits Frenkel defects due to the small size of \( {Ag}^+ \) ions.
