Statement 1: Frenkel defect is also called dislocation defect.
Statement 2: Frenkel defect is shown by ionic substances in which cation and anion are of almost similar sizes.

A

B

Statement 1 is true, statement 2 is true, statement 2 is NOT a correct explanation for statement 1.

C

Statement 1 is true, statement 2 is false

D

Statement 1 is false, statement 2 is true

Text Solution

Verified by Experts

The correct Answer is:
C
Frenkel defect is called dislocation defect because smaller ion (generally the cation) is dislocated from its normal site to an interstitial site. It is shown by ionic substances in which there is large difference in the size of ions e.g. ZnS, AgCl.
