(i) Frenkel defect create a vacancy defect at its original site and an interstitial defect at its new position.
(ii) Frenkel defect is stoichiometric point defect.
(iii) Frenkel defect is also called dislocation defect.
(iv) Silver halide shows Frenkel defect
Select the correct statements :
Imperfections in the solid state compounds are known as defects. In the Frenkel defect, the cation moves from its site and occupies an interstitial site. In this type of defect, density remains constant whereas dielectric constant increases.
There are four stoichiometric defects namely, Vacancy defect, Interstitial defect, Schottky defect and frenkel defects.
Frenkel defects is also known as dislocation effect because a cation is dislocated. Silver (I) halides show frenkel defects.
So, all the statements are true.
Hence, opt. C is correct.
