It occurs in ionic compounds with sizes of cations and anions almost equal.

(A) Frenkel defect occurs in ionic compounds where there is a large difference in the size of ions,specifically where the cation is much smaller than the anion. Option $A$ is incorrect because Frenkel defect is characteristic of compounds with a large difference in ionic sizes,whereas Schottky defect occurs in compounds where cation and anion sizes are almost equal.

MHT CET 2022 All MHT CET

A
It occurs in ionic compounds with sizes of cations and anions almost equal.
B
The density of solid crystal and its chemical properties remain unchanged as no ions are missing from the crystal lattice as a whole.
C
The crystal as whole remains electrically neutral because equal number of cations and anions are present.
D
The ions of ionic compound must have low co-ordination number.
