Q. Assertion :Frenkel defect is also called dislocation defect. Reason: Frenkel defect is shown by ionic substances in which cation and anion are almost similar sizes.

Ionic lattice has two major points defects, (1) Schottky (2) Frenkel defects. Schottky defects occur due to the cation-anion pair's missing from the lattice sites. Frenkel defects occur when an ion leaves its lattice site and fits into interstitial space. The neutrality of the crystal is being maintained and we considered all losses from interstitial positions.

The structure is shown here represents :

Cations are present in the interstitial sites in ...........

(a) Frenkel defect (b) Schottky defect

(c) vacancy defect (d) metal deficiency defect

Schottky defect is observed in crystals when .....................

(a) some cations move from their lattice site to interstitial sites

(b) equal number of cation and anions are missing from the lattice

(c) some lattice sites are occupied by electrons

(d) some impurity is present in the lattice

K C l

is more likely to show the Schottky defect, while

L i

is more likely to show Frenkel defect. Reason: The schottky defect is found in those ionic solid which have cation and anion of similar size while Frenkel defect is more likely found in those solids which have the cation of smaller size.
