Schottky defect is generally observed in :

A

NaCl

B

KCl

C

CsCl

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
Schottky defect occurs in ionic crystals of type `A^(+) B` , when equal number of cations and anions are missing from their lattice sites so that the electrical neutrality is maintained. This defect generally appears in highly ionic compounds which have high coordination number. NaCl, KCl and CsCl all have high coordination numbers i.e., 6, 6 and 8 respectively. So, Schottky defect appears in all of the given compounds.
